Deluge web broken behind reverse proxy

[koolmon10]

Updated my system recently and now deluge web is inaccessible behind my reverse proxy. I can still access it directly, but I receive this error when using the proxy URL.

Using nginx and the provided reverse proxy block. Deluge 2.0b1 on Ubuntu 18.04 LTS.

same issue here, using deluge 2.0.3. Was working correctly for version 1.x

Are you using Ubuntu ppa, please update and try again. Otherwise open a ticket with error logs
