RESOLVED:
I finally figured out the issue. For whatever reason User group for XAUTH users setting in Group VPN policy was the cause. It was set to Sonicwall Administrators which its always been and its never caused a problem with GVC. But I changed it to Trusted Users and suddenly GVC started working again. Doesn’t make sense that it suddenly became an issue but at least it resolved the problem
----------------------------------------
With GVC they get prompted with the username and password dialogue box but when they enter it it fails. This happens from multiple locations. Below I have pasted the log file of the GVC client. Clearly the problem is not a user credential issue since it works from Mobile Connect. It was working fine last week. Any suggestions?Connection IP in logs has been hidden for security reasons obviously---------------------------
