Odd question, but what’s the use case if this as a browser plugin?

Oh, then something is wrong with your DNS. You should have a forwarder setup, then you don’t need two ABS servers.

Sigh…

I hate to add to this by saying I also have the same issue and not provide anything helpful.

Things that made it better?

1. Dual zone DNS. When I’m in the house or on my VPN I don’t need to go out and back in.
2. Disable Cloudflare proxy, or whatever it’s called that hides the endpoint IP.

At that price point, a mini PC. Look at Dell or Lenovo, they make super small form factor computers that will blow a Pi out of the water.

Check your system time, if it’s wrong certs go bad.
