Issue when trying to join server that I am hosting.

[raw nacelle]

When trying to join server hosted on a dedicated box I have, I get the attached errors?
Server is running in Linux, and the files were gathered by running the batch file from Curseforge in "Craftoria-Server-1.14.0.zip"
Files were then transferred to my server.
Server is running Neoforge V21.1.99
Sometimes Craftoria gives me an error saying that the client needs to be running v21.1.99 But according to the modlist I can see, that is the version its running.
Pastebin of disconnect error attached.

Note, currently trying to join through IP Address locally for now. Intent is to port forward later, when I can verify its working etc.

For the sake of checking if its something client side, I just tried to join EU2. And that seemed to have worked perfectly fine, which tells me its something wrong with my server, but im not sure where to start looking.
My server readout says on disconnect "lost connection: Incompatible client! Please use NeoForge 21.1.99"
But as far as I can see, that is what I am using?

Seems like, maybe, something went wrong in the "transferred to my server" step.

Did you test connecting to the locally installed server that resulted from running the startserver script?

About to double check that.
I swear this may well be an issue between chair and keyboard, it wouldnt be the first time i've done something daft during a transfer.

no worries, PEBKAC hits everyone, eventually, sysadmins too.

Aaaaaaaaaaaaand we seem to have reached the problem.
It must have been something when transferring it got lost.

Feck it, imma just flatten the instance and then send over everything thats currently in my server folder.
