'SSH Connection Time Out on a specific ISP Provider

I am getting connection time out when I try to ssh to my Azure VM on a specific ISP provider, not any other ISP provider. I did notify them about this issue but they do not know what might seem to be the issue.

Also tried to create a new rule to open port 22 on windows Machine, followed all Azure troubleshooting methods, disabled my Firewall, but nothing seems to work, Only when I connect to a different ISP provider.
