The cloud server is used as derp, and the tailscale client is installed at the same time. After upgrading to 1.84.0, it is impossible to connect to a series of LAN applications such as ssh and docker through the tailscale LAN.

What is the issue?

For security reasons, I closed all ports except those required by derp, especially port 22. There are often overseas IP scans. It is fast and very safe to directly ssh through the tailscale intranet.
But there is also a problem at present. After the server is upgraded to tailscale 1.84.0 and the derp server is also upgraded to the latest version, it is impossible to ssh to the cloud server from the intranet. I have tried it so far and it may be the tailscale client 1.84.0. At present, many people on GitHub have reported SSH problems. I found that it is not just SSH, but the entire intranet environment is inaccessible, including docker. Some people also reported that when the derp server and client are the same (that is, this cloud server), there is also a problem with its verify parameter. I think it may be a problem with 1.84.0. Wait and see the follow-up plan. Continue to pay attention to the issue. At present, my derp and client are both on the same cloud server.
