can't login to the server

good morning, yesterday I created an account and played, today I wanted to log in but it tells me the wrong password or account. I use the program for both, so incorrectly entered information is almost eliminated. so how to proceed?

What client is that? It does not look like the 3.3.5a client.

I didn't do anything at all and it works now. I just had to wait an hour
