Today I gave the nuget a try as I was thinking about switching back from node red to vvvv or better vl this time. Unencrypted connection works like charm, but TLS doesn´t seem to work using port 8883 on test.mosquitto.org. I tried TLS protocols 1.1, 1.2, 1.3. I tried using User/Pass. I Allowed untrusted certificates. No success. Did you or anyone else get a TLS-connection to mosquitto.org up and running?
Checked back with node red and connection is up. Broker is up and running.
@motzi can you tell me, how you tested TLS? I guess you installed a local mosquitto broker, right? Can you tell me, how you set it up? tried my local broker which works fine on unencrypted port 1833 but I can´t connect to port 8883 for TLS usage (no certificates used for now).
