Preloading collisions 0%

First of, pretty new to this and I apologize if this is the wrong category. So recently, really new, a noob, learning to develop a server for weeks and now uploading it to Zap hosting server. Lots of tutorials and then had help from Zap Hosting staffs to help connect it properly. From IP address to setting up database mysql on my server.cfg.

Finally, my server is up, has the loading the screen and all, my second PC tried connecting as well.

Problem here is, when the game loads on loading screen of my server, 'preloading collision never moves and stuck only at 0%.

Checked all the errors, all good. Staff said to try deleting the cache of the server (using filezila), i located the cache and deleted them and tried restarting. Same thing. Preloading collission is stuck at 0%.

Getting very frustrated cos i have nobody else to help me. Like i said, new to this and i have no idea how to fix it. Spent the whole night uploading my development to the server hoping it’ll be connected and ready to jump on and play. Any help will do. Please point me in the direction.

Cant seem to find a decent and proper video on youtube OR a forum about this.

Sounds like a resource issue to me - either corrupt or missing. Are there any warnings/errors in the console (F8)?
