Client stuck at "3/5 (WaitingForProcess)" when creating room on aws linux server

[SimonMarkWhittle]

I have primarily been following this tutorial: https://github.com/alvyxaz/barebones-masterserver/wiki/Tutorial:-Building-to-Linux-VPS

I have both the master and the spawner running on a t2.micro Red Hat Linux ec2 instance. I know for certain that my client is connected to the master server, that the request to spawn a room / GameServer is getting through to the spawner / master server, and that the spawner is indeed spawning the GameServer.

Nevertheless, the client stays at "3/5 (WaitingForProcess)" indefinitely. This is something we have seen happen when running the setup locally, but clicking / focusing on the window spawned by the GameServer allows the client to continue. I had assumed that the clicking required on local would not be needed when built for headless linux, but this seems not to be the case.

I have searched around for similar cases, but have encountered none. Any help would be appreciated. I have screen shots of the logs and can provide more platform details, etc. if needed.

Well I advise you to delete all exported projects and rework all work you have done! Maybe is something related to a firewal ... Or something else... try again.. try again... don´t Give UP :) Check here for more: https://github.com/alvyxaz/barebones-masterserver/issues/222

@SimonMarkWhittle did you figure this out? The game server gets spawned, but I have the same exact problem, and my VPS is Ubuntu 18.04.
