Original GitHub issue: https://github.com/amnezia-vpn/amnezia-client/issues/351

I upgraded from v2.1.2
It was working flawlessly with openvpn over cloak but after updating to v3.1.0, servers won't connect, I tried reinstalling OS on server and configuring it from scrach but it doesn't work, I'm getting "Internal error" whenever trying to connect.
I downgraded to v2.1.2 and reinstalled the OS and reconfigured, working fine again.

My device is Windows 10, server is Ubuntu 20

I enabled logs to see what was the issue, I'm reading these errors on the logs but have no clue what they mean:

debug >LOG:1696053833,I,NETSH: C:\Windows\system32\netsh.exe interface ipv6 set address 2 fd15:53b6:dead::2/128 store=active

Solution: Run Regedit and check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents Value should be 0 or 0x20.

The OpenOverCloak container version installed with 2.1.2 is incompatible with versions newer than 2.1.2 due to major changes in the OpenOverCloak container (due to the migration to a new version of Cloak).

The client connection issue when ipv6 is blocked via HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents is a completely different issue that does not affect the OpenOverCloak container incompatibility between versions 2.1.2 and 3.0.8
