Getting certificate fatal error on web transceiver

I’m new to AllStar. I set up everything the way the pdf and web pages said. Instructions are way out of date. I picked a node and clicked “wt”. I got the expected page but when I clicked to start the transceiver I got a fatal cert error. I had this withFirefox and Pale Moon. There way no way past it. I uninstalled Java pending a solution.

I’m on a PC running Windows 11 latest. The cert error came from Java.I tried disabling all of the cert security in the advanced tab. It didn’t help.

This might help. There is a PDF link within.
