How I fixed Python OSError: [Errno 99] Cannot assign requested address
When binding a socket, you see an error message like
In my case, the issue was that I was trying to bind the specific IP address 192.168.1.100 but the computer running the script did not have said IP address configured on any interface.
so I needed to change the bind IP address to either 0.0.0.0 to listen to ANY IP address or I needed to change 192.168.1.100 to the IP address of the host computer I am running the script on.
Docker container [Errno 99] Cannot assign requested address
Note that for Docker containers, either you need to run them in network_mode: host to use the host’s network systemd, or you need to bind to the container’s IP address. You can not bind to the host’s IP address from the contaienr unless using network_mode: host ! But you can forward the ports from the host, binding to a specific IP address.

[solved] docker email not working.
Added by Rajko Albrecht about 3 years ago
We start using openproject therefore we setup a docker container.
But no emails are send. We configured an outbound smtp server but it does not send any email.
in uri /health_check_/_all it tells us that openproject is ignoring the smtp settings but tries to send emails to localhost - inside a docker container a bit a problem: mail: FAILED ActionMailer::Base at localhost:25 is not accepting connections: 'Cannot assign requested address - connect(2) for "localhost" port 25' (0.000s)
- how can we fix this? Inside the openproject container of course no smtp daemon is running
- for what is the smtp host setting in configuration page when not used for sending emails?

Re: docker email not working - added by greg glockner about 3 years ago.
I work with Rajko Albrecht and can add the following details:
- We configured the email settings in the URL /admin/mail_notifications and the test email is working
- We also tried setting the following inside the Docker compose file:
The SMTP server on our LAN does not use authentication. Nevertheless, the URL /admin/mail_notifications still shows the error: "mail: FAILED ActionMailer::Base at localhost:25 is not accepting connections: 'Cannot assign requested address - connect(2) for "localhost" port 25' (0.001s)"
- Project status emails do not seem to be sending, even after verifying email settings in an individual profile
We solved the problem: OpenProject isn't compatible with an SMTP server that has no authentication. We reconfigured to our upstream SMTP server, and it's working now.

Unable to get SMTP function to work
Dear Reader,
I have a problem with the SMTP function in vaultwarden (also with passbolt, tried it if i could get that to work). I have a microsoft exchange account, and I have a SendGrid that I used to get SMTP to work. both of them donât work. I use the latest variant of Vaultwarden.
SMTP Settings in admin portal: Enabled Default: true Host: smtp.office365.com Secure SMTP: starttls Port: 587 From Address: email address From Name: Vaultwarden Username: email address Password: âthe password of the mailaddressâ SMTP Auth mechanism: âLoginâ SMTP connection timeout: 15 Server name sent during HELO: -
I have SMTP enabled on the Office account and I have enabled basic authentications. Still nothing.
I get 2 errors: [2022-09-17 08:19:25.440][vaultwarden::mail][ERROR] SMTP Connection error: Cannot assign requested address (os error 99) [2022-09-17 08:19:25.441][response][INFO] (test_smtp) POST /admin/test/smtp => 400 Bad Request
With kind regards, Mathijs
Looks like a hostname resolving issues. Could you post the Support String which you can generate from the diagnostics page?

Please try to enable debug logging. LOG_LEVEL=debug (or trace) and SMTP_DEBUG=true .
Then try again, and see what the output of the logs tell.

Still, it looks like resolving the domain seems to have some issues. Could you run the following from the docker host and see if that works?
Where vaultwarden is the name of your container of course.
I just tested sendgrid my self, and it works just fine for me.
I am not allowed to post more links because I am a new user, so I uploaded a screenshot
Ik could be me, but Iâm not seeing any ipv4 addresses. It could be that your docker config is having issues with ipv6 maybe??
I also changed your user level, so links should be possible now.
version: â2â services: vaultwarden: image: vaultwarden/server:latest container_name: vaultwarden volumes: - /home/docker/VW:/data/ ports: -8080:80 networks: ngx: ipv4_address: 172.19.0.3 restart: unless-stopped environment: - LOG_LEVEL=debug - SMTP_DEBUG=true - SIGNUPS_ALLOWED=true - USE_SYSLOG=true - SIGNUPS_VERIFY=false - EXTENDED_LOGGING=true - ADMIN_TOKEN=password networks: ngx: external: true
This is my docker-compose.yml
Hmm, i think it had something to do with ipv6. Like, it tries to use ipv6, but it canât connect to it and causes this failure.
Maybe try to add the following to the compose file.
That should disable all ipv6 within the container, maybe that will help.
[2022-09-18 06:49:08.263][vaultwarden::mail][ERROR] SMTP Connection error: Cannot assign requested address (os error 99) [2022-09-18 06:49:08.264][response][INFO] (test_smtp) POST /admin/test/smtp => 400 Bad Request [2022-09-18 06:49:08.264][_][WARN] Remote left: client disconnect before response started.

Very strange. Still looks like it canât resolve or either connect to the ip for some reason.
Could you set the logging to trace and see if that provides some more info.

Do I need to put ââ or around the smtp address or is it just plain text?
Just plain/text is more then enough, no quotes needed. Same goes for all others btw, unless there are some special characters in there or spaces, which for domains and email addresses isnât the case.
And for the authentication?
Of you refer to smtp_auth_mechanism , that can be without quotes too, but that shouldnât matter that much.
hmm. Should we try a different smtp service provider? maybe we get more info than that of office365.
with the smtp settings for sendgrid i get this: [2022-09-18 10:11:42.616][request][INFO] GET /alive [2022-09-18 10:11:42.616][response][INFO] (alive) GET /alive => 200 OK [2022-09-18 10:12:03.178][vaultwarden::mail][DEBUG] SMTP timeout error: lettre::transport::smtp::Error { kind: Connection, source: Custom { kind: TimedOut, error: âconnection timed outâ, }, } [2022-09-18 10:12:03.179][vaultwarden::mail][ERROR] SMTP timeout error: Connection error: connection timed out [2022-09-18 10:12:03.180][response][INFO] (test_smtp) POST /admin/test/smtp => 400 Bad Request

Unable to connect: Canât assign requested address
Last updated: January 11, 2023
Note: This article is for users with technical experience. For other users, please contact the ExpressVPN Support Team for direct assistance .
Users who recently changed to ExpressVPN may see an error message in their diagnostics similar to this:
MANAGEMENT: Socket bind failed on local address [AF_INET]180.168.41.175:49314: Can't assign requested address
If you see this message, the problem may be that your host file is missing some important lines. To confirm:
- Open Terminal
- In Terminal, type “ ping localhost “
- You should see something like the below: 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.064 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.069 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.303 ms
- To stop, hit Control + C
If you see an IP address that is NOT 127.0.0.1, your host file is missing some important lines. To fix this:
- Open Terminal via Spotlight Search (command + space, then type “terminal”)
- In Terminal, enter sudo nano /private/etc/hosts
- Enter your admin password. You will not be able to see which characters you input so type carefully.
- Your host file will be loaded onto Terminal. Use the arrow keys to navigate between lines in the file.
- Enter the below three lines if you do not see them in your host file: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost
- Press Control + X to quit editing the host file
- You will need to flush the existing DNS cache for the entries to be effective. See instructions on flushing the DNS cache .

Cannot Assign Requested Address: Troubleshooting Minecraft Server Joining Issues
Networking communications can come up with specific error messages, and âcannot assign requested addressâ is among these errors. This is common to Java-based client-server applications like Minecraft , a popular game in Java that communicates with the server and other machines using TCP and sockets.
This error is down to specific issues such as busy servers, troubleshooting issues, busy IP addresses, DNS problems, and local ports which do not have binds. We will walk you through how to identify and solve the problem.
What Does âCannot Assign Requested Addressâ Mean?
Common causes of the âcannot assign requested addressâ error, how to fix the âcannot assign requested addressâ error, advanced troubleshooting for âcannot assign requested addressâ error.
âCannot Assign Requested Addressâ means that operating systems reject PuTTYâs parameters when they are invalid for constructing a network connection. The error usually occurs without PuTTY attempting to make any connections or when an attempt is made to connect to an invalid port number. Â
The error message might appear when IP addresses are incorrect, and ports need to be correctly forwarded, or when running an address, and the subdomain is pointing to a non-local IP for your device, i.e., not 192.168.x.x
âŚalso read: How to Get Cave Only World in Minecraft [ver. 1.8 â 1.16 â 1.19]
Common causes of a âcannot assign requested address errorâ are incorrect mapping, busy IP address, DNS problems, and local ports which do not have binds. It can occur while using web and application servers such as WebLogic and Jetty.
Typically, the port is in use, or the requested local address cannot be assigned. The port might be busy because something has already started using it (another instance of the server), or another example left the port in the CLOSE_WAIT state.
In addition, The message âcannot assign requested addressâ suggests that the hostname/IP you try to bind does not resolve to a local network interface.Â
Troubleshooting the common causes of the error can help in resolving the issue:
- Examine your mapping order before starting up your server.Â
- Cross-check your port number if there is a mismatch or an incorrect number.Â
- Check if the ports are correctly forwarded.
- Check the hostname linking your IP address.
An error like this indicates that the IP address is unreliable. It is also possible that there is a mismatch. To fix the error, do a correct mapping before starting your web server/application Server. When you start your Web server, it listens on a port. For example, jetty listens on 8080 8084 for HTTP and HTTPS traffic.Â
These are responsible for binding a socket to a port and local address. Also, the hostname you give them (dev host or localhost) is what they use in Linux or Windows to resolve the domain name into an IP address. Thus an incorrect mapping in this order would bring out the error message.
The most important thing is not to confuse the âcannot assign requested addressâ error with an address already in use. Refrain from assuming the two processes are listening on the same port when you get this error. Try to recall the mapping by thinking of the hostname to IP address resolution issue, and cross check content of the âetc/hostâ files in both Windows and Linux.Â
