WMware Horizon Client for iOS - Can't connect to server using mobile data

[quriouss]

Good day,

Today I've discovered that I'm not able to connect to my company server to use my VDI if I'm using my 4G mobile data as the internet connection. I receive the following message:

"The horizon server connection failed. Couldn't connect to server..."

However if I connect to my home WiFi, the connection works immediately. Please find an excerpt of the logs below:

I've also attached the entire log file (it may contain logs from successful logins through WiFi).

I've also found out that if I use my Windows 10 laptop through my mobile data hotspot, the same error occurs with the Windows 10 desktop app. Not sure if this has something to do with my mobile carrier or the server connection or the application. Everything works through WiFi though.
