[12:00:45.400] ------
I also have an window told me that:
Could not establish connection to "10.101.169.215".
TRY:
I had tried to install vscode-server manually, but no effect
I delete the file .ssh/known_hosts, nothing happened.
I think the problem maybe my OpneSSH, so I run ssh username#10.101.169.215 in
,got
"ssh: connect to host 10.101.169.215 port 22: Unknown error"
I have been searching solution about "ssh: connect to host 10.101.169.215 port 22: Unknown error", but found nothing.
What should I do to connect my remote server sucessfully ?
Any help will be appreciated.
