Hi,

It appears to be related to ExpressVPN. When I disconnect from the VPN, all is ok. Once connected, the issues happen. Is there setting in Firefox under DNS over HTTPS that I should be at. It currently is set at Default Protection.

Thanks

Great detective work! If you have no further questions, mark your above answer as the resolution and have a nice day.

Hi,

Is there setting in Firefox under DNS over HTTPS, or anywhere else that I should have set to allow me to browse while connected to my VPN and not be stuck on "Performing a TLS handshake"? The solution to disconnect defeats the purpose of having a VPN.

Thanks

I don't know the answer to your question but this link may help.

I have set my DNS over HTTPS setting to OFF from the default and it has fixed the issue. I am using ExpressVPN's DNS servers for my queries. Like I mentioned earlier, this was not an issue for me in earlier versions of Firefox. Only since I upgraded to 123.0.1.

Thanks
