Hello! I think I have detected the problem. Is related to WPA Group Rekey Interval. I observed that the unreacheable host problem started at the moment when the log indicated that the rekey had been executed. I changed the Time interval for rekeying GTK parameter to 0 so that the private key will not be valued and it has not failed again, although it is true that the wifi is now a little less secure. As soon as I can I will try to post the bug to see if a solution can be found.
