Hello @Trent Becker ,
Thank you for reaching out. If I understand it correctly your P2S VPN is intermittently dis-connecting with error Provider Error 3399942148: The server or proxy was not found
. You can try below mentioned troubleshooting steps and see if they help resolve the issue.
- Perform a packet capture at both Client side as well as Azure VPN gateway. This might give you more information on exact cause of this issue. You can use tools like Wireshark to perform packet capture at client side and you can follow this documentation for enabling packet capture on your VPN Gateway.
- If above step did not help troubleshoot the issue and if already not tried. Can you try re-installing your VPN Client? and see if that helps resolve the issue. If you have any other working P2S VPN, comparing VPN client versions might between them might help as well.
If this does not help resolve the issue, creating a support ticket with us will be helpful as a support engineer can take a look at the backend logs to help debug the issue. If you do not have a support plan for your subscription, please refer to my private message below.
Hope this helps! Please let me know if you have any additional questions. Thank you!
