The configuration of the system: RT-AC66U with Merlin 380.70_0 with active OpenVPN server and client.
No external access (from WAN), through OpenVPN/LAN only. SSH is active for LAN side only also.
When connecting to server using OpenVPN 2.4.6 latest Windows client the access to web interface is OK, but once you are going to access OpenVPN client tab in VPN settings the whole web interface "freezes" for several hours - you cannot connect to it. SSH freezes in the same way, but OpenVPN server works.
