OpenTTD JGR 0.23 Server connection issue

[Olionkey]

Hello! So I currently own a dedicated openTTDJGR server, which has recently changed physical machines and location. Since the move of the server the players of my server are starting to notice problems where they are unable to connect at all, or the speed is at 10Kbs. While others join, they are able to do it instantly and without issues. And all that has changed between the two servers, is the location and the speed of the connection to the server. I have had this issue for the past few days and can not figure out what the issue or the root of the problem. If anyone can help me out that will be greatly appreciated.
