Seeking Help with "net/http: request canceled (Client.Timeout exceeded while awaiting headers)" Error on Docker Login


I am configuring a Docker Registry using Nexus Repository Manager and have successfully been able to query the registry’s catalog using API calls. I used the following curl command to query the registry’s catalog on port 8086:

bashCopy code

curl -X GET http://<Nexus-Server-IP>:8086/v2/_catalog

This command successfully responds, providing the expected result. However, when attempting to log in to the same server using the Docker client, I encounter the following error message:

Error response from daemon: Get https://<Nexus-Server-IP>:8086/v2/: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

The docker login command used was:

docker login -u <username> -p <password> <Nexus-Server-IP>:8086

Here, <username>, <password>, and <Nexus-Server-IP> have been substituted with my username, password, and the IP address of the Nexus server, respectively.

  • The version of Nexus Repository Manager in use is 3.66.
  • The Docker client version I am working with is 24.06.
  • All requests have been made from within a WSL (Windows Subsystem for Linux) environment.

While the API call using curl operates correctly, attempting a docker login results in a connection failure due to a timeout. I would greatly appreciate any insights into the cause of this issue and potential solutions. Please let me know if there is additional information I can provide.

Thank you.

The only suggestions I can think of:

  • Docker client requires HTTPS for logins and at least your curl is http.
  • If Nexus is running on the same Windows host as WSL the default Windows firewall settings will not allow the connection.

if your are in the same machine try using localhost instead of the public ip ithink its will work,
