I am trying to set up PeerJS Server on the free accounts of either Cyclic.sh or Render.com. (If you know of somewhere else please let me know). For example, I can make a GitHub copy of PeerJS Server, then set up a Cyclic.sh account with that Github link, but it does not seem to start and listen. It returns a 500 result when I try to interact with it from my frontend. Can anyone give a dummies guide to setting up PeerJS Server for either of these free Cyclic.sh or Render.com accounts?
