    Hi @Sai krishna 

    Thank you for posting your question in the Microsoft Q&A forum. 

    The message The bot encountered an error or bug is quite generic, which makes it hard to determine what’s actually causing the issue. 

    Based on community feedback and similar cases, there are a few areas you may check: 

    -Verify the bot endpoint configuration and try restarting the App Service hosting the bot to clear any transient issues. 

    -Check whether a VPN or proxy is in use, as network interference can sometimes prevent the bot from reaching required services. 

    -If this issue occurs specifically with a QnA bot, ensure that the LanguageEndPointKey configured in the App Service matches the Language Resource key in Azure. A mismatch here has been known to trigger this exact error, as discussed in this thread The bot encountered an error or bug. To continue to run this bot, please fix the bot source code. -… 

    -In the Azure Bot Service resource, open Channels and check the health status. If the channel shows any warnings or errors, this may indicate a service-related issue

    I followed below steps to restart the app service but the page showed me no lists. Is it because of permission issue?

    Go to https://portal.azure.com

    Open App Services
