What is the kvs URL?

I pay for the cloud storage of videos,but trying to view a video and the error kvs URL failed to load pops up and I can’t view the video. Wondering what this means, how I fix it, and whether I should just cancel the subscription because there is no point paying for stuff that doesn’t work

Probably something from a service eufy uses for steaming the videos:
