I also ran into this problem yesterday with a container that was working prior to 7/26/23. My issue seemed to be stemming from FastAPI at first glance but what I found is it actually came from a dns support package called dnspython.

Seems to me whatever they updated on 7/26/23 is the source of this issue. For me forcing an earlier version of dnspython solved my issue.

As @Philip Rago mentioned, the error is with the dnspython package.

Try executing the following command-

pip install dnspython==2.3.0

This installs the version of dnspython prior to the latest one that is causing the error.

  • I installed dnspython version 2.3.0 but I'm getting another error : "AttributeError: module 'httpcore' has no attribute 'CloseError'" Do you have an idea on how to solve the issue ? – hotips Aug 20 '23 at 07:17
  • No idea, but it's definitely got to do with version compatibility. Maybe you can experiment with the older versions of dnspython or httpcore. – Sachin K Rao Aug 22 '23 at 04:25
  • I tried but I still get errors. I will retry once again with a new conda environment – hotips Aug 24 '23 at 14:36
