I am hosting publicly: icarus.tetradrachm.net.   When I followed the directions on the aforementioned guide, I did not get any errors.  However, when I attempt to connect my electrum light wallet to my full node electrumX server I get a green light when I choose 50001 and uncheck SSL and a red light when I choose SSL 50002.  Typing "journalctl | grep electrum" in the terminal prints, "electrumx_server.py[1069]: INFO:ElectrumX:[1919] SSL 70.181.17.94:33670, 89 total" among other TCP and SSL connections which confuses me. Perhaps my SSL is misconfigured on my light wallet end?

I know that web servers tend to have their signed certificates hosted by a 3rd party CA.  Does this apply to electrumX/electrum-server? I have not paid to register a CSR with a CA.
