Sorry for the double posting, but a colleague wanted to enter the server and the following error has come up in the server console.

Try to change the minimum and maximum of the Protocol, but it still does not work, you are using the System that is provided.

I use the system from readme.txt and do not have this issue.

Ok, I have already solved it. It was a customer error. Take it for granted. Thank you so much!
