SharedAnchorsFailed

https://github.com/oculus-samples/Unreal-SharedAnchorsSample
I packaged this project and set the Appid, then two Quest devices joined the session, created anchors, saved the anchors, and encountered an error when sharing anchors. The error code is 2. My location is China, and I used a VPN. I don't understand what caused the failure to share anchors.

As far as I know error code 2 on Shared Anchors = service/network failure, not your project setup.

Given you’re in China + VPN, the most likely cause is:

  • Meta backend (anchors service) is blocked / unstable over VPN
  • Shared anchors require cloud services + low-latency stable connection


    Maybe get in contact with Meta Support? Or ask someone else to test it to avoid the VPN issue?
