Meta Horizon App cant pair Quest 2

Hello,

I recently purchased a used Quest 2, and during the initial setup, I'm required to pair it with the Meta Horizon app. However, when I log into the app and attempt to pair the headset, I receive the following error message:

"Relay: Unexpected response payload – check server logs for details."

This appears to be a server-side issue on Meta's end.

I've tried multiple troubleshooting steps — including using a different smartphone, a different Meta account, and a different internet connection — but nothing has worked so far. To make matters more urgent, I need to confirm the device is functioning properly to the seller within 48 hours.

Given that I'm stuck at the pairing screen, how can I verify that the headset is working? Is there any known workaround for this issue, or an estimated timeline for when it might be resolved?

Thanks in advance for your help.
