I can't Connect to The API.

[çağatay aksoy]

I was developing with an API, but my demo account was closed because I wasn't trading. I wanted to open a new demo account and continue developing, but the connect request is returning a 201 error.

What's the problem?

Request;

 mt5.mtapi.io/Connect?user=....&password=....&host=78.140.180.198&port=443

201 Return;
