HSZigBee - ZigBee Error - exception in the Send function

[erniefrey]

Does anyone have the HSZigBee plug-in running on a WIndows XP machine?

I found a forum response back in October 2018 that indicates TLS 1.0 was required then, but now I wonder if Osram/Lightify has moved to a later version of TLS.

Here are the steps I tried to unsuccessfully get HSZigBee working ...

It has been a while since I tried using HomeSeer to control a Osram/Lightify light (Amazon Alexa is working just fine).
When I tried to turn a light on/off, I see the following log message:
Zigbee Error: There was an exception in the 'Send' function: The underlying connection was closed: An unexpected error occurred on a send

Then I checked to see if I had the latest HSZigBee plugin and I did.
I then went to the "Plug-Ins"->"HSZigBee"->"Zigbee Config" menu, updated the tokens (clicked on link to get Access and Refresh token, and copy/paste both from that window), then selected the "Create HomeSeer Devices". That fails with the error message:
Device creation failed, please check the log for more information.

I went back and tried to turn a light on/off, and again I get a the following error message:
Zigbee Error: There was an exception in the 'Send' function: The underlying connection was closed: An unexpected error occurred on a send

I went to the plugin and updated the tokens and then selected the "Create HomeSeer Devices", but that gives an error message, with nothing interesting in the log:
Device creation failed, please check the log for more information.

I also went to my Android OSRAM/Lightify app and verified the System Update showed the Gateway and all devices were up to date.
I also checked the message board and found there was a TLS 1.0 requirement discovered back in Oct 2018.

Any ideas on how to solve this issue?

Here is the my system/version info:

I just verified that I can control my lights using my dev/test Windows 10 machine. So it must be something specific to my old XP machine that I am running. My bet is it is likely the TLS 1.0 that is likely running there.

Does anyone know if it is possible to upgrade an old XP machine to a later version of TLS?
