All too often, my ssh session will freeze. I'm fairly certain the problem is at my end. None of the tilde commands work. In particular, ~# and ~. are nonfunctional. I can write to ssh's terminal window from another terminal window. If I kill the ssh process, I can ssh in again. The next time it happens, I will try another ssh session without killing the first one. dmesg did not show me anything interesting.

Any suggestions on how to diagnose?

I had this a lot until I added to /etc/ssh/ssh_config

ServerAliveInterval 15

Now I rarely get it.

That seems to have done the trick for me.
