"This smart device can only be controlled locally" - On single C520WS, other works fine.
I have two cameras, one was configured and installed without any issues. After configuring second one it showed "This smart device can only be controlled locally".
I reseted the camera multiple times, connected both by Ethernet cable and Wi-Fi. It keps showing this error. (I confirmed that indeed I cannot connect to it in Tapo App while outside local WiFi)
It's not an issue of router or DNS as other camera works fine.
I have enabled recording of diagnose_log on the issue camera and noticed in it this bit:

It clearly shows that DNS resolved adress of aps1-relay-dcipc-beta.i.tplinknbu.com (twice, to two different IPs) but connection failed for some reason. Straight from the box camera came with older firmware (1.2.4 or 1.1.4, i think) and upgraded fine so it clearly was able to reach the servers hosting the upgrade files.
How can I fix this? What does the error code 1206 resolves to? Do I need to return the camera to the seller and ask for another one?
Edit: had to remove dots from adress aps1-relay-dcipc-beta i tplinknbu com, or else I couldnt post due to "illegal external links". In orginal debug log adress has correct dots.
