So you made a change to add a VPN, and since then, this service no longer works?

Follow standard operations procedure. You've made a change. Something has stopped working. Back out the change. Does it work now? If yes, you can conclude that the problem is your change.

If it was me, I would check what you've configured for the encryption domain for this new VPN. My guess is that you've got an overlap between that encryption domain and the network that your other users are coming from.

Remember that I only know what you tell us about your network. In this case, that is the sum of the information in your two posts. I have absolutely no idea what you are referring to by Global or US network. Certainly, obscure IP addresses, but you have to try and give some relevant information - e.g. here, given that you've now got errors referring to encryption problems, might it not have made sense to note that you've made a recent change, a VPN one at that, and that it stopped working when you made the change?
