Can't create user on Local Server


I have created the Local Server and I can access it, but when I go to the Blynk app, and edit the Server Settings with the same I put on my Chrome, it just says:
“Reconnecting to the Server” in red letters.

It’s all connected to the same wi-fi netwok and I don’t know why it isn’t working


Is this a IP address or a DDNS url?. What poprt settings did you use?
