I inserted a wrong address to create a federation (a local one instead of a public dns) and obviously on the public server side, the federation failed.

Since then my nextcloud.log is continuously fullfilled by this:

{"reqId":"7MzEpBG2iHucoQJlwnj3","level":2,"time":"2021-01-05T19:15:02+00:00","remoteAddr":"","user":"--","app":"no app in context","method":"","url":"--","message":"Host nextcloud.home.local was not connected to because it violates local access rules","userAgent":"--","version":"20.0.4.0"}

I have tried to remove the Federation plugin but didn’t solve. How can I stop Nextcloud to try to connect to that server?

Thank you.

Steps to reproduce

1. Create a federation with a local server
2. The local server will be able to connect but the remote server which can't resolve the address will not
3. Remove the federation

Expected behaviour

Federation retries to stop when failing after a reasonable amount of time/retries.

Actual behaviour

Federation is counted forever and the log is fullfilled by fails.

Server configuration

Operating system: FreeBSD

Web server: nginx

Database: MariaDB

PHP version: 7.4

Nextcloud version: (see Nextcloud admin page) 20.0.4

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

Where did you install Nextcloud from: curl download

Signing status:

Signing status

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

List of activated apps:

App list

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your Nextcloud installation folder

Nextcloud configuration:

Config report

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

LDAP config

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Any idea on how to stop nextcloud retry to connect to an unreachable federation server?
