Bug FTB Continumm Server Glitch

[CrazyMSHD]

Hey guys, I'm currently working on a FTB Continumm 1.3.1 server and I'm having some problems. When I run the server on my computer everything runs fine, but when I get into my server host (Plox Host) it never fully loads and when you try to connect you get the error message "Couldn't validate account" and this issue can be solved by turning off online mode but I don't want to do that. Also I have tried running a different server on my host and I didn't have the same problem.
Anything will help!
Thank You!

You best solution for something like this is work with your server host provider. Each is a little different and you probably missing some vital config in the control panel for the server. But, I've seen some that require you put the server jar files in special locations.
