Running the newest build of VCSA 7.0.1 from Dec. 17 2020, I could not login to the VAMI page:
It instantly wrote “Unable to Login”
After some digging around and rebooting, I found this article:
Running all the commands and rebooted the VCSA, the applmgmt service started correctly, after the timeout was changed to 600 from 60!
After reboot, I could login as normal 🙂
