Issue with 6.1.1.1 on iPad

[ZoomUser36]

I have deployed the Zoom App through Jamf Pro to certain devices at a organization I work for. 

The devices can load the app, but cannot login using either "enter your email address", continue with Google, Continue with Facebook. 

The error message for enter your email is: Cannot sign in, please check your network connection.

Google error message: Cannot sign in, please check your network connection.

Facebook: error message 10000600.

I can, however, log into zoom though chrome and it opens the app though the browser, no issues. I can join or create a meeting that way. Why would I be unable to login using the app?

I have created firewall rules from the recommendation of the website.

I can login with the app using laptops and PCs.
