tuya_sharing.exceptions.ApiRequestException: network error:(-9999999) sign invalid

After more than a year of stability, we've come back to this nonsense. Reloading the Tuya integration will prompt a re-authentication, i.e. scan QR code in Tuya/Smart Life app, and everything will work fine again for a while, before looping back into the same error. It's a Tuya backend problem and they need to get their act together to fix this.

[dpk1987]

Same here all devices!!!!!

[JaBrDo]

I'm in the same boat: network error:(-9999999) sign invalid

A restart (with re-authentication via QR code and app) works for most devices, but my PB-AC05 air conditioner (8zolzs9d2e74rars) now only displays its current status and can no longer be controlled via HA.

Edit: Suddenly, it's working again. Let's see how long it lasts.
I'm hoping it'll last at least another year before the same problem comes up again.

[yfawaz75]

having the same issue after re-authentication it worked than it happened again after 1 hours

[simomaca-cloud]

ma ricarica su ha non funziona ?
io provo ad aggiungere hub, rimettere il codice utente ma non va dice : Unknown error occurred

[Darktemp]

having the same issue after re-authentication it worked than it happened again after 1 hours

same here. worked for 1-2 hours, then same error. Scanned again: hopefully longer.

[Ghyloos]

I also have the same issue here. Rescanning the QR code did not work. Please ressolve.

[liesr-lgtm]

Same issue. Heve to reload devices frequently, because data is not polling. And this week had to re-authenticate integration again with qr code. Very annoying behavior

[cloudburostaff]

Same here after long stable run

[vidualnet]

Same, QR reauth, error sign invalid

[DomHingston]

It's very annoying after being stable for so long. Is this a sign of things to come? Are the Chinese starting to lock their boards :)

I'm lucky to also have Tuya Local integration installed so have a partial back, for now.

[StoneFilosoph]

same here. It started today.
