Hello. After pasting my token i get this. I am using Nextcloud Hub 5 (27.0.2) and Zammad 6.0.0-1691946056.47e1e571.focal

Failed to save Zammad options:

Here's the actual error from Nextcloud log: OCP\Http\Client\LocalServerException: Host violates local access rules

[RTechSn]

Setting 'allow_local_remote_servers' => true, has no effect

My Zammad instance is on the same network, but the domain name is different from Nextcloud. They are served by the same reverse proxy. Both have IPs from one local subnet.

[RTechSn]

Bypassing revese proxy and connecting directly by Zammad's IP gives the same error.

Can you try exposing your Zammad instance to the internet?

I've tried again after an update and it worked.
