@SzkeLajos-2988 Thanks for the question, Can you please add more details about the use case that you are trying. you have not enabled Web Sockets in the App Service configuration. If you haven't already, review the BotFramework docs that detail all the necessary steps to take in ABS in order to stand up Direct Line Speech. In particular, these steps.
Thank you for your answer but I think the root of the problem is different. Please help me!

The Firefox Developer/Web Console shows the next message:

The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature.
