Enterprise App - This app cannot be installed because its integrity cannot be verified

Unable To Install 'app'. This app cannot be installed because its integrity cannot be verified.

I released an enterprise app for my organization. App worked well, but suddenly app not opened. When I reinstall and open this error showing.

Can anyone give a solution for that? Thanks.

I am facing the same issue. Does anyone have any insights on this?

First guesses would be: Device doesn't have WiFi access to internet, or a firewall is blocking access to Apple's server(s). Expired distribution profile (only good for 1 year). Expired distribution certificate (only good for 3 years).
