Ncorrect connection request credentials

Hello, I added my CTC union ICR-4103 to genieacs and when I try to reboot it, it says Connection request error: Incorrect connection request credentials,
i added following config : Admin>> Config>> New Config KEY: cwmp.connectionRequestAuth Value : AUTH(username, password) But it still doesn’t work, it says the same thing. Can anybody help me?

your formate is wrong use following example

AUTH(“username”, “password”)

Setting “cwmp.connectionRequestAuth” to AUTH(username, password) is the same as the default value for that config option. If your CPEs have already informed once to the ACS, and you still have the default inform script that came with v1.2, then the ACS should be able to authenticate with the CPE.

Start with looking at what value is set for InternetGatewayDevice.ManagementServer.ConnectionRequestPassword and InternetGatewayDevice.ManagementServer.ConnectionRequestUsername for the given CPE and see if that matches what is in the UI of the CPE.
