Webgl connection problems

VPadu

Hello everyone, hope you are doing well in these dire times.
I am writing this post because I am having a problem with a WebGL build of my Unity application.
My application works by loading a main menu and OnConnectedToMaster it proceeds to either create a new room or join a random one, loading a new multiplayer scene.
The problem is that on some computers the connection does not happen. It remains stuck on the first scene like it cannot join or create a room.
This problem happens on a computer of a person I do not have direct contact with, so it's kinda hard to debug, but I managed to make them send a log file to me and this is what I get:

It seems like the bold parts are the problem but I have no idea how to make it work.

If you guys know something about this please let me know!
Thank you in advance and have a great day!
