VPN client keeps disconnecting

GreenApple

Hello

My VPN client after it connects, keeps disconnecting at every 3, 5 or more minutes. I use it a lot to call clients over VoIp

here is a piece of log:

 [Server] Inactivity timeout (--ping-restart), restarting
Thu Dec 10 09:46:50 2020 SIGUSR1[soft,ping-restart] received, process restarting

and keeps disconnecting and eveery time appears this message

dev tun
persist-tun
persist-key
mssfix 1420
ping-restart 0
cipher AES-256-CBC
auth SHA256
tls-client
client
resolv-retry infinite
remote 194.**.***.226 11156 udp
verify-x509-name "Server" name
auth-user-pass
pkcs12 gw-udp-11156-tr8.p12
tls-auth gw-udp-11156-tr8-tls.key 1
remote-cert-tls server

I added the lines

mssfix 1420

and

ping-restart 0

but didn't resolved the problem.

Any help would be greatly appreciated.

GreenApple

At the server configuration and log I don't have access.

This is the client's log without line

mssfix 1420, ping-restart 0, keepalive 90 190
