facing a very weird issue with a number of windows 10 laptops in different geographic locations with connecting to a L2TP VPN Server with preshared key (Microsoft RRAS server).
One RRAS rras server is on-prem and other on AWS. On a good day people would be able to connect to both VPNs. All of a sudden some people would not be able to connect to either the on-prem VPN or AWS, some people would even face an issue with either of the VPNs that they may be able to connect but they loose internet connection as soon as they connect (probably a remote gateway issue). These issues are so random and any of them would start to happen on all these different laptops, no real pattern observed, the issues in some cases would go away after a while.
Already tried the registry hacks and other things from similar forums but no real solution in sight.
One important thing i would like to highlight is that we have mostly Macs in our environment and interestingly they have no issue connecting to all of our VPN servers at any give time (how ironic lol)
