License Connection through Proxy Erroring again

https://forum.lightburnsoftware.com/t/license-connection-through-proxy/41035/11?u=jeffs
The license connection through the proxy has stopped working again. Are you aware of any changes been made to the license portal network. Our white list has not changed.

The IP addresses to whitelist are these:

104.31.76.187
104.31.77.187

That should correspond to app.cryptlex.com port 443. These have not changed since mid Sept, 2020.

Nothing in LightBurn itself has changed with regards to how the proxy works. We haven’t altered the underlying license system code in a very long time.

Thanks for your response. We can now check elsewhere.
