I'm having a weird issue with Sogo, I'm able to view emails and compose emails, however when I click the preferences cog, the whole app will stall, and eventually I'm taking to a 503 error page at Cloudflare, which is where my domain is hosted.

I don't seem to have this error with any other application, and my Cloudron instance seems to function completely fine.

Any help would be much appreciated.

Thanks!
