I'm getting this message sporadically. It is prevalent during streaming. It usually stops after buffering has stabilized. Any thoughts on addressing this? It comes with different values

PID_ERR replay-window backtrack occurred [17] [SSL-3] [0_________________00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

So fa what I have done is to enter this in client conf:

replay-window 512 30

It somehow helped minimizing. However. I don't know the optimum values for this. Some article says that latency and large bandwidth may contribute. My average latency is around 150ms with 100Mbps bandwidth using fiber

Hi mark,

This depends on a lot of different things. This is probably a question best asked on the OpenVPN forums or mailing list. ... vpn-users/
