Server Error...

[CobainsDomain]

Let me start this post by saying this is the second game server I've ever attempted to setup so I apologize ahead of time if I'm naive or ignorant to any responses/questions. This is my first server with this hosting provider, the process appeared virtually the same as my last provider. I was attempting to add the "Hexxit" mod for my Minecraft server. I downloaded the .jar, mod files/folder, etc.. and attempted to upload via FTP (filezilla). Also using the forum for guidelines on how to do so, everything seemed pretty straight forward. Upload files, create mod folder if one did note exist and tell the control panel that i'd like to use the hexxit.jar.

Apparently straight forward it was not, at least for me. My sever is offline, it will not allow me to start/restart. When attempting to start the control panel says:

Sever Control
"Your server appears to be offline. You can start it; or, if you think it is actually up and want to restart or stop it, you can try that"

*Selected start the server* *hit the "do it!" button*

"Your server is actually already running! Try stopping it or restarting it instead."

^ pops up above this message:
"Your server appears to be offline. You can start it; or, if you think it is actually up and want to restart or stop it, you can try that" Status and minecraft still tell me server is offline/unreachable.

Tried stopping/starting, checked status multiple times on control panel and by trying to join the server via Technic launcher and still wont come online.

Event log provides:
Unexpected server stop

Your server stopped unexpectedly around this time. If you told it to exit in-game, this is nothing to worry about; otherwise, the last 10,000 bytes of output from the server, given below, may provide you with clues on what went wrong.

I'm positive I screwed something up somewhere as it didn't happen until I added all this. Do i need to request a sever reset, or does anyone have any ideas/steps i can try to fix/resolve this. Any feedback or information would be greatly appreciated and fully taken as constructive criticism.

Simply had server wiped, will try again from scratch. Thanks

Re-download the sever files, make sure that you open the launch file, ensure the "lib" folder has been uploaded successfully and issue should be resolved. My issue was that some files were not uploading successfully, after re-downloading the server files I was able to re-open the launch file successfully adding the necessary files and essentially resolving the issue.

Symptoms of this issue may include: Server crash, Inability to start server, error log reflecting fatal FML error as shown above.

[snivell]

This is not a fix but try and have someone else set up Hexxit for you.

[CobainsDomain]

How would i learn and what kind of fun would that be? oh and apparently some people are reporting issues with these files/libraries not downloading automatically being forced to manually do so.

[Vanderburg]

Yes, it's common for two Forge libraries not to download and the developers have posted a "fix" to their forums (They call it an EAQ, similar to an FAQ, I suppose), which is basically a direct link to the two libraries to download and install manually. I've added a note to this, and that link to the knowledgebase article.
