    • no
  • When did this problem seem to first start?
    • some upgrades ago
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)

  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • mod_security

Summary of the issue you are facing:

I want to update, but it looks like the LDAP connection is causing serious problems here, so I can no longer use the server…

Since a few updates, I can no longer configure/edit LDAP, only via occ.

As soon as I deactivate LDAP, I can update and the server is accessible, but when I reactivate it, the server crashes.

I have also tried deleting the configuration and recreating it… but I am unable to do so. The data is not checked, transferred, etc.

I am unable to proceed.

I suspect that I will have to rebuild the server.

Steps to replicate it (hint: details matter!):

  1. upgrade from 31.0.12 with my ldap config

What do you mean precisely by “crashes”?

What happens when you do so?

I note you’re using mod_security. Is that properly disabled for Nextcloud? It’s possible that’s the culprit.

Hello,
Sorry for the late reply… but I don’t work on weekends :slight_smile:

I tried several times, but I always got the message “The website cannot be reached… Error code from browser xxx.” or :Internal Server Error. The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

Now I “only” get the message from Nextcloud

I tried it now again several times and get always another end :slight_smile:

LDAP configuration in Nextcloud no longer works. This means that I can no longer see or change any configurations in the WUI.
I can only make adjustments via occ.
In general, it is still possible to retrieve the LDAP data.

Check your nextcloud.log while the problem is occurring (i.e. when the internal server error comes up). The JAERB* request ID in the error message (from your screenshot) is logged so you can see what is going on.

Hi,
I think I will create a new server and will migrate then to the new.
There are some issues like LDAP… I will switch to PHP8.3, the storage will be increased and some other things…
In this case I think it is easier to migrate.
If the migration wont work, I will let you know… because I have to fix the mentioned issues :smiley:

Many thanks for your help!!!
