Photon Voice 2 only working on local network


I am trying to finish up a VR project (Quest) that uses PUN2 and Photon Voice 2.

The voice chat was working fine, but now it just does not work. Doing a test on 2 computers on the same wifi network, the voice seems to transmit as intended. But, when testing with my team mate in a different city, we do not hear each other.

The prior version of this project, which we shipped to the client, was working as intended. We each have this old version on our Quest devices, and haven't changed it since we shipped it off. We tried running the old version to see if voice was still working, and we are no longer able to hear each other.

Please advise - this is the only thing keeping this project from being finished.

Thank you, and I will reply with results from any tests.
