I needed to use my VPN and am no longer able to connect. 

I use OPEN VPN and have TP link DDNS enabled. 

deleted the old vpn Config and created a new one, exported and still wont connect. 

Service Type UDP

VPN port 1194

VPN Subnet 10.8.0.0

Netmask 255.255.255.0

This is what ive used it he past few year with other routers as well without issue. 

Open vpn logs as follow

Connecting to [XXXX.tplinkdns . com]:1194 (XXXX) via UDP

stop tunnel requested with reason:1 Event disconnected 

EVENT: CORE_THREAD_DONE

EVENT: DISCONNECT_PENDING 

I think the firmware bricked this feature. Is it possible to downgrade?
