First confirm that the channel has been connected to a Chat. If it is not connected to a Chat, RAGFlow ignores external messages and does not generate replies.
Check whether the third-party platform credentials are correct, whether the bot has been enabled, and whether message event permissions have been granted. After credentials are modified, RAGFlow automatically restarts the corresponding channel connection.
Check whether the bot has permission to send messages, and confirm that the bound Chat can answer normally on the RAGFlow page. For WeCom Webhook, also confirm that CorpID, AgentID, and Secret can obtain access_token normally.
First confirm that the channel has been saved, then wait a few seconds to see whether the page generates a QR code. If the QR code is still not displayed, confirm that WhatsAppGateway has started and that the RAGFlow backend can access the gateway service. If the login state has expired or been cleared, scan the QR code again for pairing.
