Ok I could use some guidance on where to troubleshoot next...Here is the situation:
 

There is a typical isp 2.4 router and a TP-Link extender operational in the house. (Most smart devices I have operate on the extender, all is fine). The router is single channel, only at 2.4 with WPA2-PSK-AES encryption.
 

C110 setups and operates normally, but the phone app claims it's offline, it can't sync the date/time, I can't view it remotely, Google assistant does not see it, can't use the cloud etc.

C110's ip shows up normally in the extender app. I can also view the stream on my desktop (also connected on the extender) on VLC using RTSP. (Meaning the extender assigns an ip to it as expected?)

I obviously have done all the steps suggested by the manual like switching to google's dns (Which I don't like) re-done the setup, reset the camera, power cycled, turned off the firewall on the router, but nada. 

Additionally, I have tried to set it up using a mobile hotspot, and there it goes online perfectly, so def something is up with my network. I have zero idea where to look though, not done anything fancy with static ips, port forwarding etc, everything is a default.
 

Ideas?

Here is also a log I pulled out of the sd https://drive.google.com/file/d/1gt11x6z5KRoEH1vITjvop4k6a-TBki_K/view?usp=drive_link
