Please unban server on apps.nextcloud.com

Hello
Please unban my Nextcloud server (IP: 162.55.78.35) to reach out ‘http://apps.nextcloud.com/api/v1/apps.json’ (IP: 65.21.231.50)

Could not connect to appstore: cURL error 28: Connection timed out after 60001 milliseconds (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://apps.nextcloud.com/api/v1/apps.json

The server does not have any internet issues
Thanks

That IP is not banned.

Thank you very much
It was Hetzner vSwitch issue
Some time it silently lost the connectivity for some hosts
