6.12 on RH 7.9 - Web server won't start

[SPisani]

Hello. We tried in many ways but web server wont start. I see the server working and doing outbound connection, but it's not listening on 443.

There is nothing strange in the log as I can see.

I don't know what I can look at to fix that.

Thanks

Hi @SPisani, this request should go to support since they would need to review log information before suggesting a possible solution. 

If you can see that the demisto service is running and you can find a "server up and running, good luck to us all" message inside the server.log file it means that everything from the application side is good. I would look for a network issue. 

You need to disable the firewall to be able to access the UI. Run the below commands

systemctl disable firewalld
systemctl stop firewalld

Hi @jfernandes1. It's very strange. The server process start without any error in server.log. Using netstat I can see that it is connecting to the other system but server process is not listening on 443. Here we tried a different port. Nothing.
