Can't manual update from iview v2 mr2

Hi, Thanks for your query.

Can you please share following details

a) Platform on which you have deployed iView. e.g. VMware, HyperV

b) Have you used ISO or Virtual zip file

And can you try it once after clearing the browser history.

Hi SanketHanda 

We have installed iView on VMware esxi v6 with virtual zip, starting from version 2 build 306 then updated build 776.
The screen looks the process of uploading the gpg packages is 100% after that popping error as above. I've tried using Firefox 53 and Chrome 58 but the problem remains the same. And finally we deployed directly using virtual zip v3beta.
