Wireguard connections are lost after a few minutes

Mon Jan 4 21:49:55 UTC 2021

Wireguard server installed on CentOS 4.18.0-240.1.1.el8_3.x86_64

kmod-wireguard-1.0.20201221-1.el8_3.elrepo.x86_64
wireguard-tools-1.0.20200827-1.el8.x86_64

Since the versions released in september ?, I can see that wireguard is unstable (before, it was working fine).

The connection is lost after a few minutes, as shown in Windows client logs.

I tried to change the "PersistentKeepalive = 25" parameter with 15 or 300, but it did not change the issue
