Server Adding Custom Maps

[ThunderSn1per]

Hi guys,
I've had custom maps working on my server before but having taken a break from Killing Floor 2 for some time I am probably missing something super obvious. That said, I have done a lot of Googling and can't seem to find anything else.

I've added my custom map to my server's 'KFGame\BrewedPC\Maps\' folder, this is IDENTICAL to my downloaded map in my game installation folder under '\Steam\steamapps\common\killingfloor2\KFGame\BrewedPC\Maps\' as I copied it there myself.

I have forwarded ALL ports I can find that are mentioned in my server's 'KFGame\Config\PCServer-KFEngine.ini' file.

I have also added the custom map as follows in my server's '\KFGame\Config\PCServer-KFGame.ini' file:

[KF-Blockfort-v2 KFMapSummary]
MapName=KF-Blockfort-v2
MapAssociation=0
ScreenshotPathName=UI_MapPreview_TEX.UI_MapPreview _Airship
bPlayableInSurvival=True
bPlayableInWeekly=True
bPlayableInVsSurvival=True
bPlayableInEndless=True
bPlayableInObjective=False


Still when I try to connect to my server, through either 'open XXX.XXX.XXX.XXX' or the browser, I get the error message:
Connection Lost
Downloading package 'KF-Blockfort-v2' failed: Error opening file


What am I doing wrong here?

UPDATE:
Have managed to get passed the initial issue, however, now whenever I try to connect I lose my connection before I get into the lobby.
This is despite trying to join from the Server Browser and command line 'open localhost'
