I too have a Battery Cam Pro where only the video clips are broken. I get “Error code 05: Failed to fetch the video from the cloud”.
I have spent some time troubleshooting. The same camera works fine if I tether it to my cell phone or take it to the coffee shop, where they use Comcast internet. However it is broken on gigabit fiber for both my neighbor and for me. We use Centurylink fiber GPON.
My other Wyze cameras work fine. I bought a second WBCP to test and it is similarly broken. I’ll test it out in a few other areas to be sure.
If anybody is willing to share which ISP they are using, (and if you know whether it uses pppoe) I would like to see if this is relevant.
