Cloud Edition, Designer can´t connect

I have installed an Ingition cloud server with the setup config from marketplace.
Default is not port 8088 opened in the network settings that is configured via marketplace.
That is now added but the designer can´t connect to the gateway.
The gateway itself is reachable on port 80 and also the vm on port 22/ssh.
If i check with netstat on the vm there is nothing on the machine that listen to port 8088, is the only option to setup a ssl/tls in the network settings and use 443?

I haven't used cloud edition, but if port 80 works to connect to the gateway, then designer should also be able to connect using port 80.

That does not work either. I think I have tested most ports and settings in the gateway...
