28.0.1 6 errors shown but cant open protocol section

[faxxe71]

I have been using the Linux server Docker for about 1 year and have been doing all the updates. But since about 3 weeks I can not open the section /logging. Nothing is displayed there.
In the overview it reports 6 errors since December 28th but the log window cannot be opened or remains empty.

Otherwise there are no functional impairments.

What could be the problem with the log display?
Thank you for your help

I would first make sure you are using the latest container, then follow nextcloud’s status on their numerous issues with v28.
