We have a problem connecting to our customer’s network through openvpn. Some time after the connection is established, an error appears in the log and the connection is disconnected. Then it connects again and so on. The problem is observed only with one customer, with other clients the connection (also through OpenVPN) does not break. I also want to inform that using another provider (mobile operator) the connection does not break.
Any ideas on how to solve this problem?
