Lost Access to Host from Docker on Custom br0 after reboot

I have a few dockers running on br0 with their own IPs. after a reboot I lose access to the Host from these dockers.

If I open the console for the docker and curl to the host it fails. I then have to stop the docker service, disable the allow host access to custom networks hit apply, enable the allow host access to custom networks again, hit apply and finally start the docker service and hit apply. then everything works beautifully. If I run curl on the host now it instantly responds.

Below has info on this, and to me it is not solved...
