Error: Failed to start tunnel, could not establish a connection

I’ve ran the command forge tunnel. It leads to an error from past two days.

#forge tunnel --verbose

Hi

You might be experiencing an intermittent network issue or you may have a firewall blocking the port.
Would you be able to test again on different networks to see if it isn’t a firewall issue.

I’m testing forge tunnel on my end and am not able to reproduce the problem.
