Software (please complete the following information):

• Bazarr: 0.8.4.4
• Oscarr: 0.1.0
• Python: 2.7.18
• OS: Arch Linux

Additional context I'm using Bazarr with a custom base URL.

If I don't set the Base URL on Oscarr, I get a Unable to connect to Bazarr. Check your settings. error as expected. If I set the Base URL (either as /bazarr or /bazarr/) I get the reported error).
