I replaced the router, the extender remained unchanged.  Unfortunately I am unable to reconnect the 6-channel control panel.  It's like it doesn't reset.  After the reset the LED remains off.  The wifi network is present, but it gives me an error when connecting after entering the password.  How to solve 🙏 

This morning I had to reset the 6 zone control unit. After the reset everything is fine from the Netro app. Instead, when I log in from a PC with my account, the old setting is detected and it won't let me delete it. The system returns error nvalid group ID 33131: invalid device status.
What to do?
