I followed your instructions and all works fine, however for me, the main reason to host a server locally and offline was to be able to use the websockets (node-red-contrib-blynk-websockets).
I’ve used the same setup before on the cloud and everything is fine, was running for weeks. However when I try to do this on a local server, All works OK until node red stops. The socket then floods the log with errors until I can disable the config for the websockets in N-R and restart the service. My feeling is this is more to do with the node-red side than the server but that is only a guess.
I’m using
server 24.2 (same result with 24.1)
Unmodified server.properties file (other than usernames etc)
mail.properties
N-R config for websocket is ws://192.168.xxx.xxx:8080/websocket (also tried 8082 and changed the server.properties to match)
Any Ideas???
All im trying to do is monitor a 232 serial string incoming on the Rpi and push elements of that string out to my phone with Blynk, no other HW, Or any other suggestions that can work offline, Like I said before the cloud version works a charm…
