ZigBee Connect Error

[Jobee]

This started the other day. I have renewed my tokens, rebooted and cycled the plug in but nothing seems to work to get my ZigBee back online.

ZigBee Error:

There was an exception in the 'Send' function: The underlying connection was closed: An unexpected error occurred on a receive.

Anyone have any insight?

I fixed this.

In my effort to tighten security, I disabled TLS 1.0 & 1.1. Turns out ZigBee is still using 1.0 so when I re-enabled it, everything started working. I hope they update the protocol to use TLS 1.2 since 1.3 is now approved.
