SSL VPN - Connection Issues
Hi there, we are having trouble with both Netextender and Mobile Connect, they connect to our SSL VPN once, then subsequent attempts to re-connect (after disconnecting) fail. Netextender with the error Verifying user…authentication failed! and Mobile Connect with the error Failed to fetch the domain list from server. It doesn't seem to have any real repeatable behavior and because it connects and operates fine once, it seems like some sort of timeout/refresh issue in the Sonicwall rather than a configuration issue?
We are using a TZ300 router on FW 18.104.22.168-53n.
Due to the Covid crisis we have been trying to connect users to our network from their home PC's which aren't joined to our domain. I'm thinking that possibly changing User Authentication Method from LDAP + Local Users to Local Users only may help? Any other ideas to make it a little more reliable, please?
