Can’t connect to Homebase cameras via remote wifi

I have 2 indoor, a floodlight, a doorbell and 2 eufy pro cameras in my set up. I can view all cameras on mobile data and WiFi when at home but whenever I go to my parents house, I can only view the cameras that don’t require the homebase on their WiFi connection but when I switch to mobile data on my phone I can see all of them. Any ideas on what’s going on?

I remember someone said there was a setting in their modem/router combo that blocked the IoT and once they changed that setting then they could view the live streams when away.
