I’m triggering a script from my controller machine to be executed in my agent machine. the script involves connecting and disconnecting of VPN services, which results in a ChannelClosed error. the connection gets established after a while
but I was wondering if Is there a way I could prevent this, by extending retrying or delaying the ping interval to the agent machine, such that the connection doesn’t get closed.
