Hi @Friendica Support
friendica quits with an error 500 (internal error) and don not show anything special in the logs...
What can I do?

last entry in the application logs is from yesterday evening, it's a warning

2023-02-13T23:01:51Z worker [WARNING]: Invalid URL {"dirtyUrl":"https://https:mastodon.social","worker_id":"3facd10","worker_cmd":"UpdateGServer"} - {"file":"GServer.php","line":509,"function":"cleanURL","request-id":"63eac0f5978a0","uid":"b8b1b6","process_id":17853}

apache_error log:

I have absolutly no idea how to debug this.

I'm on the dev branch.
