If the API doesn't work, rebooting the hotspot you're trying to control will often fix it.

I've had that happen several times over the past couple weeks.  It seems to be related to the work/upgrades currently being performed on the server.

Understand that, during this time, they may be working on the underlying code, restarting services, etc.  This can disrupt the API's functionality.  Rebooting the hotspot drops and reestablishes a connection to the server, allowing the API code to "re-find" it.

Examples include (but not limited to) using the "Talkgroup Drop" function on Robert/Mitch's TGIF hotspots, using the API code to change talkgroups, etc.
