Steps to reproduce

1. I tried to send a federation request from an intranet nextcloud instance (not visible on the web) to another visible on the web
2. On the latter instance the federation request is received but fails for obviously reasons ("[no app in context] Warning: Host nextcloud.home.local was not connected to because it violates local access rules"
3. Nextcloud seems to be trying continuously to contact that remote instance fullfilling the logs with the error.

Expected behaviour

One or more retry, then fails and stop trying.

Server configuration

Operating system: Ubuntu 20.04

Web server: nginx

Database: mysql 10.3.22

PHP version: 7.4.3

Nextcloud version: 19.04

Updated from an older Nextcloud/ownCloud or fresh install: fresh install

Where did you install Nextcloud from: latest.zip from nextcloud website

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)

Hello @szaimen yes, I do confirm the issue is still there with the latest release.

I have removed the federation app from my installation but Nextcloud is still trying to connect to the remote server.

Could be related, except I could not ever instaurate a federation with the remote server since the hostname is unresolved.

After reading the other issue a bit more, I think the mentioned issue really quite similar so I'd recommend to close this one. There was also a workaround mentioned: #14797 (comment)
