Check comp-lzo option both server and client configuration file. If “comp-lzo” is off in sever.conf and it’s on in client.conf, then a bunch of messages is appeared in server log.

Good luck.

PS.

I strongly recommend to remove comp-lzo option. This option makes some troubles. (i.e. ping / icmp packet).
