could not resolve hostname

[afgman4]

i saw about error that..

bitbucket ssh : could not resolve hostname aaa.bbb.com non-recoverable failure in name resolution

i tried to add etc/hosts  like this

xxx.xxx.xxx.xxx aaa.bbb.ccc

and then.. that's show me the error message.

so i tried to add like this

xxx.xxx.xxx.xxx aaa.bbb.ccc:22

but... i didn't fix that.. how do i?

When I connect with Eclipse, it works fine, but when I try to connect with vscode, I can't connect. I only get this message "bitbucket ssh : could not resolve hostname aaa.bbb.com non-recoverable failure in name resolution" Why is that?

I'm afraid that is purely a problem with your networking settings.

Bitbucket is asking your operating system to connect it to a named domain, and your DNS system is saying "sorry, can't do that - I can't resolve aaa.bbb.com"

What is the difference between the settings you have in Eclipse for reaching remote computers and the settings in VS Code?
