Memsql upgrade to version 7.1.11 making master node down

Hi All,

I am looking a help to up my master node. I upgraded memsql version from 6.5.12 to 6.8.22 every thing was fine.
Once upgrade from 6.8.22 to version 7.1.11 then upgrade throw error on last “Currently on state OfflineClusterUpgrade.OfflineClusterUpgradeFail”
master node is still down.
Is there any configuration file changes causing the issue to bring master node up. both leaf node are showing UP.

Thanks,
Shishir
