I have a question, not sure if you'll have an answer. I set up Haven in Portainer and I'm able to connect to the endpoints via web browser (through Tailscale, not reverse proxy). However when added to clients notes don't get sent to it. Any ideas?
Discussion
I am not familiar with Portainer or Tailscale, apologies. What I would suggest is to test that your relay is able to accept websocket connections at all prior to using with a client.
I have a section here where I am setting up a relay with auth, and test the connection with wscat.

If all else fails open a GitHub issue with the devs. Utxo and Anthony are quite responsive
