When I try to run a command -- (for example: sfdx update), I get the following message on the cmd prompt:
Attempting to contact update site.. S3 host is not reachable..
Has anyone here come across this message earlier. Any inputs would be greatly appreciated. Thanks!
This is a proxy issue. Had same problem here on internal network (with a nasty proxy), switched to guest network and didn't have it anymore and it got updated successfully.
In my case problem was that Visual Studio Code was running updates at the same time. After VS completed and restarted a few times, I was able to run >sfdx update
