client cant communicate with server / constant dropouts

Post by heap » Sun May 21, 2023 1:19 pm

Hi,
i didnt touch any configs... what happened is that client constantly having / losing connection to the Server - results are packet loss.
I have no clue what is that? why i randomly happened? The connection between client/server is w/out any packet loss.

All what i can see in the logs is that Read is broken ? while doing ping ...

any idea how to debug that?

Code: Select all


root@roon-core:/var/log# tail -f openvpn/roon-server-openvpn.log
