What does "port is already mapped (on Android)" or "Could not Open Port (on iOS)" error mean?

This could happen if we try to open port forwarding in an already mapped port. Since we are using a random port with every test and closing it afterward, this error is rare but might happen if another service forwarding this port in the network.

If you see this error, we recommend running the compatibility test from scratch again and it would use a different port for the next test.
