Hi guys!
I have an automation account created by my client and have started scheduling automatic updates for a group of linux machines.
It was successful except in one machine, I wanted to verify the problem by connecting with azure-cli (via powershell on my local pc) with the command
az ssh vm --ip 10.xxx.xxx.xxx
But nothing happens, I noticed that I can no longer connect to any of the linux machines to which I started the scheduling except two of them.

I tried to reset ssh with the command
az vm user reset-ssh --resource-group linux_test --ip 10.xxx.xxx.xxx
rebooted the machine and now it asks me for the password that I don't know which one it refers to since mine does not accept it .
Did the update do something to the ssh service? How can I be able to connect to this group of linux machines again?
Thank you and good day!
