The issue you are facing:
When browing the log via /admin/logging, log entries seem to load correctly.
However, after a few seconds a popup message is shown stating “Neue Einträge konnten nicht abgerufen werden.” (could not fetch new entries).
The log file shows multiple messages that look like this:

These entries keep popping up as long as I keep the logging webview open.
Is this the first time you’ve seen this error? No:
By analyzing the log file with grep I found that the issue first started on 2023-08-28 (almost a year ago), when I conducted some major updates. Analyzing the “version” tag in the log entries, it seems that I upgraded from 25.0.2.3 to 27.0.2.1 on that day using multiple incremental steps).
They still appear today, after I upgraded to 29.0.4 (so it’s not related to some old and unsupported version).
Steps to replicate it:
- Open /admin/logging in any webbrowser
- Wait a few seconds
The output of your Nextcloud log in Admin > Logging:
See above.
A new log entry of this kind is generated every few seconds, more specifically whenever the logreader-main.mjs script generates an XHR to Login – Nextcloud<req_id_here>.

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.
Isn't this the same as /admin/logging that I already described above?
Further information:
I originally described this issue on GitHub ([Bug]: LogController fails to poll after some update · Issue #1330 · nextcloud/logreader · GitHub).
I was told that this most likely is a configuration issue, e.g., related to opcache.save_comments. Therefore, I quadruple-checked my php.ini (both /etc/php/8.1/fpm/php.ini and /etc/php/8.1/cli/php.ini) and found no obvious flaws:

I went on to also check my webserver configuration and found no mistake visible to me. I took special care with this step after finding a similar issue on GitHub ([Bug]: NC28 syntax error accessing /settings/admin/logging · Issue #1073 · nextcloud/logreader · GitHub). This issue is large and mixes up several individual problems, but many people seemed to have issues with correctly serving mjs files. I made sure that this part is correct in my nginc config:

I am accessing Nextcloud through a reverse proxy so there is no HTTPS in here.
