Nextcloud version (eg, 12.0.2): 13

The issue you are facing:
I have an otherwise functioning NextCloud instance, which will not sync to and from external storage when using the Windows desktop client. It has no problem syncing files stored on the server itself. However I have attached a Digital Ocean Space using the external storage plugin. Every time the desktop client tries to sync files stored in this location, it errors out with a “503 Service unavailable” message. The Android client works fine, however. I can upload a file to the external storage from my phone and view it in the web interface. However I can’t do the same from Windows.
The problem began after I enabled TOTP. Before that, I was able to upload and sync from external storage just fine. However removing TOTP did no good. I tried removing the external storage and re-adding it as well as deleting and re-installing the Windows desktop client to no avail. Setting SELinux to permissive did not help either.
Is this the first time you’ve seen this error? (Y/N): N
