The log message indicates a misconfiguration in the HSRP setup. The correct configuration requires the HSRP virtual IP to be set to 10.1.1.1. This IP address is used by hosts on the network as their default gateway and is shared among routers in the HSRP group to provide redundancy. If the local router's HSRP virtual IP is not set to 10.1.1.1, it would not match the group's configuration, leading to errors and potential network issues.
