Steps to Reproduce:
Do you have an ssh config file set up?
@roblourens yes I have been using it fine for 6 months then the other day the panel is empty. I can鈥檛 select a new host or previous directories or start any port forwarding.
I did notice a pop up saying that the ssh explorer extension was no longer needed and not long after that it stopped showing
Same problem here.

"Remote SSH: Connect to host" works and correctly shows all hosts from ~/.ssh/config
Can you check that the SSH extension is up to date? And are there any errors in devtools? (Help > Toggle Developer tools)
Any idea @alexr00?

I don't know whether that error is related, @sandy081 does it look familiar?
If you open a new local window do you see any difference?
Yes, the error disappears in a new local window.

Just saw that too:

/cc @alexr00
The error seems unrelated and is tracked as https://github.com/microsoft/vscode/issues/79809.
Somehow the remote explorer isn't getting all the views the way I expect it to.
I wasn't able to repro, can you include steps @alexr00?
Or someone else who saw it can confirm that it is fixed in the latest insiders build?

I'm not sure how it's happening, so I don't have any repro steps.
I have checked my system and it is now showing the remote hosts and port forwarding as expected. Thanks @alexr00!
Thank you @SSmale!
