Ahh I see, so the issue is more precisely
a. I am located at R2 and reboot router 2 and lose my connection via wireguard to Router 1
OR
b. I am located at R1 and reboot router 1 and lose my connection via wireguard to Router2
OR
c. I am located at R1 and via wireguard reboot router2 and lose my connection via wireguard to Router 2 ( wg doesnt come back after reboot )
Normally after a reboot, there should be a slight delay and then wireguard reconnects is my understanding so need to figure out the correct scenario.
