[Hidan]

Hi guys.
I do not know if I'm posting in the correct area, but if it's not, I apologize. since now.
please move to the correct area.
I'm having difficulty logging into my server.
I am using virtual machine with amazon ec2 ubuntu system.
but I have already done all the necessary process so that everything of certain. but when trying to connect to the server, I type the login and password, and it appears, it was not possible to connect to the server.
I do not get any error in the ssh command panel.

Thanks in advance

Fixed problem.
For some reason my ip was blocked. because I could log in to phpmyadmin using normal ip, but the server could not.
I find it strange that my friends can do it.
Solution: I had to change my ip.
Thank you all.

Check the IP and the Port in clientinfo or sclientinfo

Check the PACKETVER in the mmo.h of the src folder, then the clientinfo.xml.

I have already done these processes and also can not connect, I have configured the client version and ip in clientinfo.xml but I can not connect. and the ports are released, is it because I'm using the free azure and amazon hosts? because I tested in amazon and azure of microsoft and not being able to log in.
