No WiFi, No Firmware original

Unfortunately, I have a big problem with my toniebox.

I had to reflash the Toniebox with Teddycloud. Everything worked really well. I entered the IPs and SSID and password.
However, after booting, the box does not connect to my router.
I have tried countless times.
The second problem: I no longer have a backup of the original firmware. Is there somewhere to download it? How can I get the box to work again?
Many thanks for your help

If You have done the flashing using the gui, the Backup should be in teddycloud in the Firmware volume.

You might reflash your box with the original Backup, re-setup the wifi and then do the flashing again (and leave wifi things empty)

I think I messed up pretty badly.
My Toniebox is not visible in my Teddycloud.
Is there any way I can save the box?

Can I still reflash and release the SSID+PW?
Would that help?

What have you done?

Have you flashed the original backup? Have you connected the box with this unmodified firmware with your WiFi?

Did you leave the WiFi fields in the flashing empty or not?

Please be more detailed.

I have finally flashes the original file. Wifi field was empty.
But the box does not manage to log into the wifi.

I also tried a new setup with the Toniebox app. The app starts, all SSIDs are listed and I enter the password. No matter which SSID I select, I always get the error message ant.

Do you have any other ideas?

Then you might Check the ca.der.

Get it from the box and Check if it’s from boxine or from teddycloud. If from teddycloud, then check if it’s the same as the one in your teddycloud CERTs Server folder.

Hmm can you please assist me?
How can I get it from the box? And do you know the path of CETRTs Server?
