idk what is but rtspt streams are not playing or intermittently playing
rtspt://stream.vrcdn.live/live/ is the common part of all urls i have had issues with
rtsp is main protocol,
rtspt is tcp only variant
rtspu is udp only variant.
test all of them on your stream to see if you’re using the protocol you desired.
rtspt://stream.vrcdn.live/live/SuharpyVR would be a good example of what mine might look like 
rtspt is used in vrc and dosent work it at clubs so cant change it and i put rtsp into vlc to make it works
