I’m having trouble connecting to a new PERP light server, it tells me “refreshing for SMFID.”
Then it reconnects me to the server and does it over and over.

Here’s how to fix your problem:

Step 1. Go to the hoster’s forum and ask there.
Step 2. Be patient.
Step 3. Profit.

Well of course that was the most logical course of action to take first, that has already been done and they do not know the issue. Facepunch seemed like the next logical step so far and that hasn’t quite worked either. Time for waiting.
