Failed to authorize using the OAuth service: Resource temporarily unavailable

I noticed that my Docker backups to OneDrive had stopped working back in October, so I checked the Duplicati logs and came across this error:

"2025-03-13 15:42:21 -07 - [Error-Duplicati.Library.Main.Controller-FailedOperation]: The operation Backup has failed with error: Failed to authorize using the OAuth service: Resource temporarily unavailable (duplicati-oauth-handler.appspot.com:443). If the problem persists, try generating a new authid token from: https://duplicati-oauth-handler.appspot.com?type=onedrivev2\nUserInformationException: Failed to authorize using the OAuth service: Resource temporarily unavailable (duplicati-oauth-handler.appspot.com:443). If the problem persists, try generating a new authid token from: https://duplicati-oauth-handler.appspot.com?type=onedrivev2"

I can telnet to the OAuth server just fine. I’ve tried restarting the Docker container, creating a new backup, regenerating new AuthIDs and re-adding Duplicati access on OneDrive itself, but the same issue still persists.

Hi @flypinoy7, welcome to the forum :wave:

This sounds like a network issue, so I am guessing that this is some kind of network issue on your end. I can’t rule out an issue of the server, but I can see lots of activity, and you can visit the site and see that it is working.

Based on some searching for the error, I have found a thread that says this can happen if the DNS settings prevent a lookup of the hostname:

Can you try using nslookup from within the container to see if you can resolve the domain name?

Thanks! I’m actually running Pi-hole in another container on the host so there might be something with the configs that are causing the issues.
