"Logon Failed” with new update

After the latest update to the current version I now receive a “Logon failed” error, every single time. I use a RD Gateway that allows me to connect to a computer on a different network. Worked like a charm until the latest update. Has anyone found a fix for this? Or is there a link to download a previous version? I read one person had to revert to a previous TimeMachine snapshot with the older version to get it working. Doing that just doesn’t sound like a reliable option..
