Uploading custom map to server?

I am looking to make a flat custom map and put it on my server but I don't know how to upload it can someone help me, please.

 

The host I'm using is GTXGaming

You must upload it to file hosting with direct file link
After that open server.cfg file and add a command server.levelurl "DIRECT LINK TO YOUR MAP FILE"
I think that will work.

Hi! @Spada

1) Stop the server
2) Delete the map in the Steam folder (maps)
3) Check that you have deleted all files in \server\identity
4) Import the .map into Dropbox: Transfer file, go to "Files", click on "Share" on the .map file, create a link, copy the link.
5) Modify the server.cfg with the following parameters: (Paste the link of the map in the leverlurl without forgetting to change the end value dl = 0 by dl = 1

server.globalchat True
levelurl "https://www.dropbox.com/s/1j5v186m720kmr4/test.map?dl=1"
server.saveinterval 300
server.secure True
server.headerimage "http://www.yoursite.com/image_500x256.jpg"
server.url "https://www.gtxgaming.co.uk"
server.radiation True
decay.scale 1
