I use Visual Studio Code (now version 1.111.0) from a Mac Studio. Most of my development is via SSH to a number of servers. Beginning today, connection attempt to any of those servers produces error "Connecting with SSH timed out." Yet all of these servers are reachable via SSH from a terminal running on the same Mac.

Researching this issue, I found that some have resolved similar situations (one host, though, I haven't seen mantion of en masse) by removing ~/.vscode-server/bin and its subsidiaries via:

rm -rf ~/.vscode-seerver/bin)

But although I have now done this on all remote servers, the issue persists for me. Note that this is across-the-board for at least seven remote servers that all worked yesterday. I had done only one software upgrade recently: latest version of xcode, on mac demand. (But I have since reinstalled vscode locally (meaning on the mac). The remote servers are a mix of linux (Ubuntu, Raspbian) on various hardware. The Mac is at latest level.

Besides removeing remote .vscode-server, what might I try?
