Can't resolve HTTPS over onboard SIM only ?

Hello looking for some experts to provide some feedback on an odd issue I'm trying to pin down.

Laptop - on board Verizon SIM - VPN SW Client back to office* - Able to ping resource on local office LAN by IP and Name and also 182.13.x.x traffic by IP and Name
*Note: Also a vendor specific router off in-office firewall interface that certain and all 182.13.x.x data gets routed to/through.

Connection via on board SIM connection - CANNOT resolve a https:\\listenerpage.domain.com site.
Connection via Hot-spot on cell phone - CAN
Connection via a external Verizon Jet-pack newer or older model - CAN
Connection via hard wire/LAN connection within the LAN - CAN

Tested on two different same manufacturer Laptops, Panasonic, and same behavior (success vs unsuccessful HTTPS address resolution) outlined above.

Packet Monitoring shows drop on successful HTTPS resolution attempt but nothing really that can denote why other than its not getting a response back it seems.  Wire-shark shows packets can be no bigger than 1378 when being transmitted, but it's same when successful using another method to get out to internet by Verizon.  Of course all vendor support says 'not them'.

Any thoughts on what else to look at consider, angles to approach would be greatly appreciated.

I must pay a $5 monthly Access Point additional fee for my HUAWEI USB stick for it to connect over VPN.  I am paying for an Access Point to prevent double NAT in my USB Cellular connection. Ask Verizon if you need to pay an Access Point fee.
