Creality Box - wifi not connecting

Ender Series
1

Hi group,
I need help connecting my Creality Box (WB-01) to my Ender-3 (SW 2.0.8.6 / HW 4.2.2).
I was able to connect my phone to the Creality Box, but when giving my home wifi password the Creality Box isn’t able to complete the configuration. Here are the steps I’m following:

  1. Inserted TF card
  2. Connected the Creality box to my Ender-3 USB port
  3. Connected power to Creality Box
  4. Yellow light in Creality Box is blinking, green light is on and still
  5. Found Creality Box wifi in Creality Cloud app, in my phone
  6. Succesfully connected to the Creality Box wifi
  7. Found my home wifi (2.4GHz) in Creality Cloud app, proceed inserting my home wifi password (several times checking correct password)
  8. I see the green light blinking for a moment, than it gets still again
  9. I get the error message in Creality Cloud app, “network connection failed”.
    What should I do?
    Thanks.
