Hello, we use a Sharepoint 2019 on Premises farm (minirole with two web servers and two app servers, ha-proxy load balancer, https terminated on the web servers) with different browsers. With Firefox (currently the ESR version) we keep getting the error message "PR_CONNECT_RESET"
It is impossible to reconnect with F5, but if we have an open tab on another side of the sharepoint, or if we copy the address bar and open it in a new tab, we can continue working.
What could be the reason for this error message?
