Suddenly during the past 24 hours, I can’t get past the “pairing phrase” screen on Lightning Terminal Connect. My node is connected, and I can see where the pairing phrases get generated. I can revoke old sessions. The Terminal connect has been working great for weeks, but suddenly I just can’t get through. The pairing phrase is correct. But the app only returns this error message inside a big scary orange box:

“Failed to connect.  
Not connected. Failed to connect the WASM client to the proxy server. Try reloading the page or obtaining a new pairing phrase.”

In the past, when that happened once or twice, I would just Re-Start the Lightning Terminal app within my Umbrel homepage, and things seemed to clear up.

But this time I have tried uninstalling and re-installing the app. I have cleared my Windows browser cache. I’m not using a VPN or any unusual blockers.

This is the default proxy address; is there any other that I might try?  
mailbox.terminal.lightning.today:443

I am running on a Windows computer, otherwise I might have installed Aperture to create my own proxy server address.

Any suggestions?
