7007 Offline error suddenly fixed

Hi everybody, sorry if this was posted a lot…just wanted to check if somebody else had this situation. So I left my phone to record as usual and 400km after went to check the live feed… I got Wake up camera, offline, and 7007 errors, could not connect it for days. Today I opened app after almost 10 days, and everything seems to work perfectly. What could be the reason for this? I thought that maybe power went down and phone ran out of the battery… Anybody else had this? Thanks!

P.S. and back to error again…

Yes I have had the same situation so now its hard for me to check on my kids new baby sitter or check on my mom

This happens on my iPhone when the WiFi crashes and router needs restarted.
