T4XG series not able to autoprovision over https with FreePBX 14

[JaredBusch]

You can see this thread on the FreePBX forums for all the details.

But to summarize: The Yealink T42G and T46G will not correctly communicate to over https FreePBX 14 with a Let's Encrypt Cert.

Neither for autoprovisioning https://pbx.domain.com:1443, nor to pull a remote phone book https://pbx.domain.com/contacts.xml

If I change it to http for those, it works perfectly.

If I connect to a FreePBX 13 instance it works perfectly with https or http.
