Description Luke-Jr 2021-09-12 18:41:13 UTC

It appears the built-in SSH tunnelling cannot handle more than 1 connection at a time. With 1 session connected, any further attempts fail. Closing the first connection allows one to succeed in its place.

This bug exists in at least 20.08.3, 20.12.3, and 21.08.1.
