Windows 10: Cannot connect to Server 2019 VPN through Verizon hotspot.

Hi.

I have a new Server2019 server which I have installed Remote Access / VPN on. Everything works correctly through my home network CBTS and through other services Spectrum, etc.

But I have clients that need to connect to the VPN through their Verizon hotspots. When I switch my PC to my Verizon Hotspot, I get the following error trying to connect:


The VPN connection between your computer and the VPN server could not be completed. The most common cause for this failure is that at least one Internet device for example, a firewall or a router between your computer and the VPN server is not configured to allow Generic Routing Encapsulation GRE protocol packets. If the problem persists, contact your network administrator or Internet Service Provider.


I have been trying to work with Verizon 2nd level support, but have had no response.

IS there something I can check on my end to try and troubleshoot this issue?


Thanks in advance

No Internet Connection When VPN Is Connected

This particular issue has been going on for almost a month now. My companies IT department is still trying to figure out the root cause. Below is a list of isolation / troubleshooting i've done.

Issue: Once connected to the work VPN (successfully) the internet connection on the Windows 10 machine disconnects and does not allow any network traffic.

OS: Windows 10 Home - Version: 1909 (OS Build 18363.476)

Computer: Razor Blade 2019

- Latest drivers installed

- Latest Windows updates installed

- System Wide issue

Troubleshooting / Isolation

• Cellular Data: Verified the Windows machine can connect to a hotspot and successfully browse the internet. (No VPN involved)

• Cellular Data + Work VPN: Verified the Windows machine can connect to the hotspot & successfully connect to work VPN and successfully browse the internet.

• Home WiFi: Verified Windows machine can connect to the home wifi network and successfully browse the internet (No VPN involved)

• Home WiFi + Work VPN: Verified Windows machine can connect to home WiFi. It can successfully connect to work VPN. However once the work VPN is connected, the home WiFi network indicates (No Internet Access)

• Ping Test + Work VPN: Verified I can successfully ping (work) websites and even the work VPN URL successfully without any packet loss. However once I go to ping (non-work) related addresses like google.com, apple.com etc. there is packet loss.
  

At this point I decided to test my work VPN on my iPhone & Apple Mac.

• iPhone: Home WiFi + Work VPN: Verified the iPhone successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

• Mac: Home WiFi + Work VPN: Verified the Mac successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

Isolated: Only the Windows machine seems to be affected. I even verified this issue occurs on multiple Windows user accounts on the Windows 10 machine.

- Windows 10 is fully updated to the latest November Windows 10 update and issue persists

- Deleted and Added the VPN configuration several times and issue persisted.

Third Party VPN Client Test: Tested with Nord VPN and the Windows machine successfully connected to the home WiFi network & the Nord VPN connection successfully connected to a random server and successfully browsed the internet.

- Disabled IPV6 on VPN & WiFi network configuration (Per IT Support guidance) and issue persisted

*Currently updating to Windows 10 Insider Preview 19033.1 (vb_release) to see if this might fix anything pertaining to Windows 10 VPN.

Thanks for any additional guidance / suggestions / help that the community offers.
