Hi @nodomain,
I experienced the exact error as in your post below. The request to user avatar for example https://example.com/user_avatar/example.com/myself/96/215_2.png response with 500. In my case, the domain name example.com is not setup in public DNS, in the testing stage, I spoof example.com in my host file locally. Will this issue not appear when the domain name example.com got setup in public DNS?
