After some out-of-band discussion, it appears that the VPN @alliswang is using via Shadowrocket is blocking QUIC connections. Since iOS recently updated to use libQUIC, relying solely on QUIC for communication with the Service Node network, the user is now unable to use Session when the VPN is on. Session on other platforms is still functioning via the VPN because Android and Desktop versions have not yet adopted libQUIC for communication with the Service Node network.
