Connection Issue
Hello.
Starting from saturday the 11th of May clients stop the connection suddenly for two times. Last was yesterday at about 20.15. When i noticed that all client disconnected i was able to acces the server and simply doing a Reconnct from OpenVPN GUI the client started to reconnect. This happened saturday 11 of May at about 19.15 too. The server/client configuration never changed since last one year an everything worked fine.
No modification was applied to firewall NAT and rules, neither in the server or client config files.
The only operation recently done is renewing server certificate on May 5.
The clients are control devices with enbedded open vpn (not user computer or workstation).
I'm using OpenVPN 2.5.5 based on Windows 2019 server.
Looking at the server log, i started to see some errors and warnings that probably refers to NAT issues according what i've found in variuos forum and in your support website. E.G.:
read UDP: Unknown error (code=10054)

I attach the server configuration, one client configuraqtion file and server log.
I'm planning to restart my main firewall and network connectivity devices but i won't be able to do until tomorrow.
Thank you in advance for a feedback.
