Answer 1

Two things that could be happening that I think of when I see your logs:
Enterprise apps need a network connection to verify the certificate. The device needs to be able to connect to https://ppq.apple.com. Are these devices online or behind a firewall?
The way to trust a certificate on a device changed over the years. Does the device trust the enterprise certificate?
This link should give more context about these two issues: https://support.apple.com/en-gb/HT204460
