Consistent HTTP 400 error when trying to join a specific game on mobile

What is the issue are you having?
My game can only be launched and played on computers while it supports all platforms. Players on mobile, for instance, can click “Play” and launch the game but their game ends up crashing.

Does the bug happen 100% of the time?
In a certain place, for mobile platforms, yes.

If so, are there steps that reproduce the bug?

  • Go to the game’s page on the mobile app (iOS/Android).
  • Press the Play button.
  • Observe that the error in the screenshot below occurs and you cannot join the game

Where does the bug happen?
Phones and tablets (Haven’t tested in Console)

Is it level-specific? Is it game specific?
Yes, it only happens in this place: Extreme Skydiving V.2 - Roblox I have tested the game in a different place, it worked really well

Would a screenshot or video help describe it to someone?

When did the bug start happening?
Right after I turned mobile and tablet access on. (The game was available on PC when it came out)

You know what they say, sometimes all you have to do is to think simple. Anyways, all I had to do in order to fix this bug was to turn off access, wait couple seconds and turn it back on. It is fixed.
