We are seeing issues with Windows clients which have been running a lower version and then upgrading to 3.4.0.
Once they upgrade the client connects however after 30-60 seconds the client stays connected - shows as connected on the client however no IP traffics passes. They then get an IP connection and it works again for 30-60 seconds and it repeats.
We found installing the older version works for some but not all client. It is like it internally breaks the connection. We have had to use the command line version which appears to work?
