Describe the bug
I just tried out the new security features and after enabling the new "Block AI and Crawlers"-feature, my Nextcloud is not able to sync via CalDAV anymore. I only get an error message on Android, but nothing in Zoraxys logs.

If I enable this feature for my Authentik host, some clients can not log in anymore, Vikunja for example (Internal server error). Maybe the same issue.
"Block common exploits" works fine for those hosts.

To Reproduce
Steps to reproduce the behavior:

1. Have a running Nextcloud
2. Enable this feature
3. Try to sync contacts or calendars via CalDAV / CardDAV
4. HTTPS web UI works fine, only CalDAV / CardDAV sync does not work anymore

Expected behavior
Sync without errors :)

Host Environment (please complete following information, DO NOT REMOVE ANY FIELD(S)):

• Arch: AMD64
• OS: Ubuntu server 24.04 x64
• Version Zoraxy v3.3.0 branch
• Are you using Docker? No
