Hi, I'm new to set up a VPN router and need help. I bought a TP-Link ER605 and CyberGhost VPN service, but I can not find a place to show me how to set up TP-Link ER605 as an OpenVPN Client to connect

After updated firmware, MS Edge in Windows 11 can not be used to open ER605 v2 setting page. It asks to update or using another browser. It worked well before the firmware updating. Firefox works.
