I'm still getting "invalid cloud password" for a C110 in HA after following the instructions

Update: So it turns out my router only says that it's blocking internet access, but it still allows access to certain services. Google and Youtube still load, but the results don't. Since it's a TPLink router, obviously, the cameras get through too, so...useless.

I blocked internet from my router. Factory reset the camera by pushing the button until the camera said "reset complete, restarting camera." Verified that the internet was blocked when I added the camera back to the tapo app and it said "this camera can only be controlled locally." It only did this for the first camera I did this with, I assumed it was because I had cleared the...notification?

Anyway, I set the cameras back up, set up the account and verified that I get video from the RTSP stream in VLC. I even deleted the "tapo_control" folder and replaced it with the latest version, just in case.

I'm still getting "invalid cloud password" when I try to add it in HA though. I know for a fact that the password is right, I copied it from my password manager.

In the camera that I got the "local control only" notice with, the firmware is 1.3.14 Build 240513 Rel.45784n(5553)

edit: I have 6 cameras set up, I only reset 3 of them. 1 of the cameras shows firmware 1.3.11, but the other 2 show updated to 1.3.14. I'm beginning to wonder if I actually blocked the internet correctly...the one that has old firmware knows that it's outdated, who knows why it hasn't updated, updates aren't turned off.

Upon further messing about in my router, I finally figured out their convoluted way of blocking access, rebooted everything several times and finally managed to get what I was after. There was no actual issue, just the router being dumb, so I'm marking this as closed.
