Public bug reported:

Server: openvpn 2.4.7-1 (Raspbian 10.2)
Client: ubuntu 19.10 (openvpn: 2.4.7-1ubuntu2, network-manager-openvpn: 
1.8.10-1)

My server is using google authenticator via pam as second factor beyond client 
certificates.
After 1 hour (which is the default value of reneg-sec) my client tries to 
reauth to the server and the authentication fails.

Expected behavior: client should ask for pass(token) after unsuccessful
auth and/or client should have an option not to cache password and ask
for it before trying to reauth.

Workaround: set reneg-sec to 0
