Greetings,
We are developing a multiplayer game using Unity Game Server Hosting, Photon Fusion 2, and Unity Matchmaker. However, we are facing an issue where players cannot connect to the server after successful matchmaking. This problem persists in both development and release branches, with no differences in server configurations, matchmaker rules, or game builds affecting the outcome.
Our investigations have ruled out our codebase and Photon Fusion 2 as the cause, as connections fail consistently across different build environments and local server functions work in the development environment. We experienced a similar issue a few months ago, which resolved itself after a short period.
In summary, players were able to connect to the server, but they have been unable to do so for the past 2-3 days. This issue likely stems from Unity’s systems, as the release build’s multiplayer functionality also stopped working without any changes being made to it.
