I noticed that after a few days all client still exist but the information about connection is empty and I no more can connect to the router (Screenshots are applied), please help me solve this annoying problem, thank you in advance.

Wierd.

Well, when you create the client the router generates entries for the client and stores it in nvram. You can check the entries by ssh:

nvram show | grep wgs1_c1

(Replace c1 with c2 for 2nd client a.s.o)
Whenever it starts the server it uses select entries for the server config.

For the client config, im not sure if this is taken directly from the nvram variables, but a copy of the client configs are at /etc/wg/. Check if they are there by:

ls /etc/wg | grep .conf

But the client config is actually not needed for the server in order to start.

Finally, check what wireguard includes in its config, and what peers are included:

wg show wgs1

You can also check the server config, more complete:

wg showconf wgs1[/conf]

So, are your peer nvram variables still there? Are the "missing peer" still included in the running server?
