How do you enable node creation?

I’ve got this weird issue with my server. On my home server, my android application works perfectly; it can connect, register, create nodes and get nodes.

However, on a server I just recently bought, I’m unable to create or get nodes. My application is able to register accounts and even log into the server, but can’t create a node.

Is there some setting I need to activate to enable nodes? I can’t seem to find anything different between my home server settings and my purchased server settings.

All ports are open by the way.

Any help is appreciated.

Thank you!
