ACS Chat channel failed to connect

I have tried to connect the Azure Bot to Comunication Services Chanel. I would like to create a connection for whatsapp, but I have got this error:

"ACS Chat channel failed to connect. An unexpected error occurred, please try again."

Unfortunately, the Microsoft Azure has not given to me more information.

Can you all help me?

The error could be due to misconfiguration, permissions, or service health issues. Verify if the bot is properly registered in Azure Bot Service. Disconnect and reconnect the bot or restart the associated services.

Follow below steps to connect Bot to the Azure communication services, refer the article.

• Create an Azure app service, Azure Bot and Azure Communication Services.
• Create a sample Echo Bot, provide the below values in your configuration file.

AppSettings.json in C# Bot:

{
  "MicrosoftAppType": "MultiTenant",
  "MicrosoftAppId": "<MicrosoftApp_Id",
  "MicrosoftAppPassword": "<MicrosoftApp_Password>",
  "MicrosoftAppTenantId": "<Tenant_ID>"
}

• Deploy the bot application to Azure App Service.
• Connect the Azure Bot to App Service by configuring Messaging Endpoint.

Test the Bot in web chat:

Navigate to Bot=>Settings=>Channels , select Communication Services - Chat=> Connect, select/create Communication Service:

• Able to connect the Bot to communication service:
