 Keep in mind that it's your web browser connecting to the MQTT server, so you need to provide a hostname that is reachable by your web browser (ie if your BBS is running on a VPS, then localhost won't be a good choice for the Hostname, unless you plan to remote into that VPS and launch a browser from there). Keep in mind that it's your web browser connecting to the MQTT server, so you need to provide a hostname that is reachable by your web browser (ie if your BBS is running on a VPS, then localhost won't be a good choice for the Hostname, unless you plan to remote into that VPS and launch a browser from there).

 My understanding is that the SSL certs created by the Synchronet Let's Encrypt client can be converted to a format that is usable by Mosquitto, but I haven't investigated that because I run a separate client to handle my SSL certs.  If someone else goes through the conversion process, please add the steps/commands here! My understanding is that the SSL certs created by the Synchronet Let's Encrypt client can be converted to a format that is usable by Mosquitto, but I haven't investigated that because I run a separate client to handle my SSL certs.  If someone else goes through the conversion process, please add the steps/commands here!

 +It is VERY important that you DO NOT open any of the MQTT ports to the general public.  Sensitive information may be published to some topics, and other topics allow controlling your BBS (eg downing nodes).  So please make sure your MQTT ports are behind a firewall, and if you want to make use of the Web Monitor or Node Spy features, then only IP addresses belonging to you should be allowed through.
