I can't connect to the ports on the GCP server.

[mikey5]

I have a Windows 2019 server set up, and the latest MySql database on it.
On the server, I opened port 3306 for all connections.
I also added an engress rule in VPC allowing connections from ip 0.0.0.0/0 to all ports.

Despite these actions, I am unable to connect to the database on the server.
The telnet command also fails.
The ping command, on the other hand, works without a problem.

Even if I disable the firewall on the server completely, it doesn't change anything.

Can you advise me what could be the cause of this? I have put mysql server in GCP instance before and I don't remember having such problems.

Hi @mikey5 ,

Based from the description of your issue/problem, there might be no issues with the VPC or with the firewall rules. You might have to check if the server's memory is full, making it inaccessible.
