Using Firefox with a VPN yields PR_END_OF_FILE_ERROR
Using Windows 11. I'm using a free Proton VPN. My Firefox version is 103.02. I want to be able to continue to use the VPN when using Firefox to check my gmail accounts. If I disconnect the VPN, Firefox lets me access my mail site without a problem. When I use the VPN connected, I'm getting a PR_END_OF_FILE_ERROR
Is there a way to keep the VPN on and connect with no error? Is there a Firefox setting I can change? I don't have proxy selected in Win 11 connections. Cache is cleared.

Disabling Firefox DNS over HTTPS allowed me to connect without error, while using Proton VPN. Thanks!
