[SOLVED] TCPCLIENT intranet connection fails if no cloud connection

[ScruffR]

I don’t think Particle.process() is the cause because at least with system thread enabled, which you should set, you can call it even when not connected to the cloud and nothing bad happens.

With or without SYSTEM_THREAD(ENABLED) Particle.process() won't cause any trouble.
But other commands (e.g. at least Particle.publish() used to) should be wrapped in an
if (Particle.connected()) { ... }
