Failed uploads

Why last two month i have so many events failed to upload ? Or …on event page i see 13sec video but its actually only 5-6sec long ?Some clips even 2-3 sec. Cam+ subscriber.

First thing its my wifi ,right :grin:? But…i tried to use rules and trigger recording, 14 V3 cam’s simultaneously upload perfect 12 sec video. Anytime, never errors. always 12 sec .
Last firmware/app version.

All cam’s power cycle on daily basis, i tried to re-add cam+ …always same .On the end i canceled Cam+ ,worthless.
