I am migrating Road Warrior clients to the latest community client v.2.6.10. I am having a problem with one (not all) of the users migrated. The one user is able to connect but cannot browse mapped drives in Windows Explorer. Windows Explorer becomes “not responding” and has to be shut down. The last item on the client log.
openvpn write udp no buffer space available (WSAENOBUFS) code=10055"
On the server side, I’m seeing these errors logged, but nothing related to the user in question.

I rolled back the one user to the OpenVPN client he was running, but that has not fixed the user’s problem. Am I missing something?
