Clients can't connect to port 80 under Linux

We have a web client solution built on Servoy 3.0. The solution works perfectly on Windows, but when we run it on Linux, clients can’t connect if the solution uses port 80. If I change the http port to 8080, the clients can connect fine. We want to use port 80. Right now the solution is running in Servoy Developer, not as a service.

Are you starting it as root? Non root users cannot run stuff on port 80 on linux.

That was easy. Thanks, Jan!
