Institutional instruction and 'Sorry you are visiting our service too frequent'

I’m teaching a weekly class at a college using Unreal Engine for virtual cinematic production. Every week the students have to login into their accounts to be able to use the Launcher and Quixel Bridge (using an Epic Games account) since the classroom computers are wiped every day. Half of the class is unable to login due to the ‘Sorry you are visiting our service too frequent, please try again later’ error and waiting 5 or 10 minutes (we can’t afford to wait any longer) doesn’t solve it.

I can imagine this is due to the login servers seeing too many login attempts from the same IP address (shared by all the computers in the classroom) but I was wondering if there is anything that can be done to fix this. It’s very unlikely we can get individual IP addresses for each workstation in the classroom. I’m sure we are not the only ones teaching UE4 at an institutional level so I wonder what other schools are doing to avoid this.
