vRealize Business update checking hangs

Trying to update vRealize Business 7.2 I noticed that it hangs during update check with the message "Checking for available updates...".

No matter what I did - changed the update options, reboot the appliance - didn't help. Looking on communities.vmware.com I found the post 477322 which presented the same behavior, only for vCenter Server Appliance and it was from 2014. So I tried (a bit skeptically) to start the update from CLI as suggested in the post:

• ssh to vRB appliance 
• /opt/vmware/bin/vamicli update --check
• /opt/vmware/bin/vamicli --install latest --accepteula

And it worked:

I suppose this workaround can be applied to most of the appliances.
