Warning: Potential Security Risk Ahead | Unreal engine academy site

I got this warning from my firefox browser when i tried to access it from the learn tab on the epic games launcher.
Afterwards, i have also tried accesing it from my phone and other browsers on the pc, but they all show the same error.
Any advice on how to avoid this? or any info on why its happening or when will it be fixed?

Attached is the firefox screencap, sorry if its on spanish
