Running behind a SWAG reverse proxy (nginx) using the LinuxServer docker image for nextcloud.

I have the same problem. I am using a docker image of nextcloud (NEXTCLOUD_VERSION 25.0.4) and NPM as reverse proxy.

Maybe it must be a cache Issue ?

[ChristophWurst]

yes

[joshtrichards]

Do any of you on this issue have the full raw log entry (stack trace)? That's really needed to track down things like this.

The latest mail update really helped a ton with issues I was having, but it appears that there is still a cache issue that is making the pages unresponsive after I delete mail.

What's the process to get this info for you?

[dustbro]

This is still bogging down the email client :(

[joshtrichards]

What's the process to get this info for you?

Either from your nextcloud.log directory or via the Log reader app by clicking on the 3 dot menu to the far right of a log entry

[dustbro]

@joshtrichards Here's the log: nextcloud (2).log

[dustbro]

I believe this is also exhausting my mail provider bandwidth. Nextcloud mail is using 1.3GB of bandwidth daily
