Can’t access to same room in photon

I’m developing match making system in Unity using Photon. But suddenly, I can’t access to same room even if I check that I’m accessing same room.

⚠️ This solution assume that you already have Photon in your project.

Here is the solution:

Window → Photon Unity Networking → Highlight server settings

You can see Fixed Region box.

Type only one region to fix region. (You can choose closest region where you are) Then, you’ll see your server works.
