Is there another landline network you could try? It should though work via a mobile network tether. If you have tried all the troubleshooting it seems that this camera could be defective.
Where did you purchase this camera (the retailer) and which region? Can you remember how long ago since you bought the camera as well and have any order/sales references.
No, I don’t have any other landline network I could try it on. I bought it from Amazon Spain in November 2019 from this seller: https://www.amazon.es/sp?_encoding=UTF8&asin=&isAmazonFulfilled=1&isCBA=&marketplaceID=A1RKKUPIHCS9HS&protocol=current&seller=A3LDXR48R7LTSM
The camera has been sitting, wired off, for a long time - untouched. Will someone please provide a firmware file so I can try that? The other cameras I have working have the version 4.6.0.0A_201908271549 installed - I’d really appreciate if someone could provide that version’s installation file (already tried the latest one from the support page, got no luck).
I believe the latest one is that which is listed on the support page https://www2.yitechnology.com/firmware/index
Different cameras, although the same model, could have different firmware if for example there is a difference in how old they are.

Hello! I have tried everything, I am also having this problem with my camera. I set the camera up about a week ago and everything was running smoothly. I woke up one morning to it not being connected anymore on the app. Now every time I try to pair it just says pairing time out. I connected the support email, but haven’t heard anything back!
Good evening
I had a problem with my Iphone app and I reinstalled the Yi Iot app and hit the reset button on the 1080 PTZ Home Camera.
I repeat that everything worked correctly before the reset. Now he says “Pairing has timed out. Please reset the camera.”
I confirm that I am connected to the 2.4 wifi network with which everything was working yesterday. I have seen that many are having this connection timeout problem. I did all the necessary tests, changing the phone, restarting the modem, deactivating the 5ghz antenna etc.
I followed all the advice and procedures of these pages and the respective links. But nothing to do. The help center replied to restart tel, modem, etc. but they are procedures already done. Everything worked perfectly before performing a reset due to the uninstallation of the app. Are there any reliable solutions for this problem that I see has affected many customers? Is there the possibility of forcing a reset via SD? is there a firmware that can be written by forcing its installation? the ticket number is 572652
Hello what brand of camera are you using if you are using the IOT app?
Thanks for coming to the community for more info. It is a little difficult to ascertain what camera brand this is based on the photo. Is there any other information you can send in regards to the brand of the camera?
