Should I downgrade from 0.20.1 to 0.17.1?

[miyu4u]

I've upgraded Netmaker to 0.20.1, but it seems to be quite unstable.

I'm using Netmaker to construct a k3s overlay network, but ever since the version was upgraded to 0.20.x, communication has become highly unstable. I'm not sure if it's due to the newly added TURN and STUN.

The flannel keeps disappearing and agent is constantly terminating abnormally due to node IP errors. I'm honestly fed up with checking and fixing this.

Although 0.17.1 has NAT settings, I don't use them because they make the network communication unstable. However, from version 0.20.x, these related settings have disappeared.

I'm aware that the latest version of netcliet does not support backward compatibility. So, would it be better to downgrade and pin both the server and client versions? Or should I wait until this problem is resolved and stabilized?

I don't need any new features. I just want the mesh network configuration to communicate well with each other. But everything seems to be getting more and more difficult....
