cyberpanel cannot be accessed from Google Cloud Platform

I have Installed cyberpanel in my GCP Instance. The installation run well.
But the admin panel cannot be access.

I have opened the TCp port 8090 in the firewall rule, but still cannot be access. The error was:
This site can’t be reached
35.196.xxx.xxx took too long to respond.

Anybody can help me solve the problem…? Thanks!

I Check the port, and 8090 already open. But still cannot be accessed.

You need to open port 8090 at GCP firewall too.

Yes, I did. I tried to use tag and no tag. But the problem haven’t gone

But Still cannot be accessed.

You have done something wrong on GCP side, subtmit ticket with your GCP login if you need our help.

And how did you allowed port 8090 on server side? As you don’t need to do this, port 8090 is opened during installation.
