I get the attached error seemingly randomly when i go to certain vendor webpages like automationdirect.com and seeedstudio.com. I can not find anything online as to why this might be happening. it is a work computer with ESET Endpoint security.

The try again button rarely works, i need to close firefox completely and reload the webpage to fix it.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
