    • nginx
  • PHP version (e.g, 8.3):

    • 8.3.29
  • Is this the first time you’ve seen this error? (Yes / No):

    • Yes
  • When did this problem seem to first start?

    • I reinstalled Nextcloud
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)

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

    • Not that I know of

Summary of the issue you are facing:


WebDAV endpoint

Your web server is not yet properly set up to allow file synchronization, 
because the WebDAV interface seems to be broken. 
To allow this check to run you have to make sure that your Web server can connect to itself. 
Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. 
This failure may be the result of a server-side DNS mismatch or outbound firewall rule.

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

Not sure if it’s replicable.
