Error: Error installing mod 'NS2c' (download failed: 28)
Been trying to set up a modded server though Multiplay, some errors are being produced that I've never seen before. Does anyone know what Error 28 is and how to solve it?

CODE

And its not just NS2C.

I've tried mods like No motion blur and Minimal Alien Vision and they've downloaded without issue. So it seems like it effects larger mods.
I also have a few phantom entries in my WebAdmin (like blank entries in the Mods list in-game ... )

    Multiplay emailed UWE yesterday, no reply yet. Found some others with the same issue who weren't able to fix it either, so that's helpful.

    This can happen if there is a proxy between you and the outside world. I had to do some fiddling in squid before my server beat the error 28.

    I suspected it to be a networking issue, but why would it download correctly for some mods (smaller file size) but not even begin for others.

    I have seen the error 28 issue since my mod went up on workshop, from my testing you could resolve it simply by starting and stopping the server a couple times, to me it almost seems like there is a short timeout set for mod download, and larger mods can easily exceed that timeout.

    Can confirm this also happens for MvM mod.

    The timeout must be tiny, I've tried restarting the server plenty of times. :(

    An aside: The WebAdmin needs work.
    Need a search for workshop mods, some sort of indication that the mod is downloading or is going to be downloaded. Don't have non map mods appear under the "Maps" tab and fix all the blank entries that appear. Pretty sure the check box does nothing as well.

    Well I'm stuck. Anyone hosting NS2 in Australia? Hypernia won't do it and Multiplay won't reply to my emails. Hohoho.

    Jekt - can you download the mod to your client and then FTP up the stuff to the server?
  • JektJekt Members, Squad Five Blue, Reinforced - Shadow Join Date: 2012-02-05 Member: 143714Posts: 1,543 Advanced user
    Don't have FTP access to Multiplay servers, even if I did the mod wouldn't update if I uploaded it manually. I'd likely get the same error.

    for co mod, i can download it yesterday.
    for ns2c, you can download it via workshop yourself with your game and then copy it into the mod folder in your server. a temporary workaround.
  • JektJekt Members, Squad Five Blue, Reinforced - Shadow Join Date: 2012-02-05 Member: 143714Posts: 1,543 Advanced user
    Yeah I was able to download combat mod yesterday as well. Still error for NS2:C though.

    I have the same problem.

    Can't download Combat or NS2C

    I tried searching through all files in the NS2 Server folder for the mod downloading code using strings that were printed in the console, wasn't sure if it'd be in an LUA file etc.

    It looks like it might be inside the Server.exe so can't view it.

    I am not sure if it's using the steamclient.dll so when I get some time I will check if I replace that from my machine maybe if there is any difference.

    I will also next maybe setup some tcp dumping to see if I can determine what traffic the Server.exe is sending and whether there are any headers for HTTP that might have some information.

    It would be nice if the NS2 Team though would look into this, I don't know if I am going to get much out of these tests, I don't use any proxies and it's only certain mods that have problems...

    Most maps don't seem to have any problems except with regards to the Combat Mod collection I get this error for "co_Core remake (Alpha 3)"

    But I get this error with the actual Combat mod and NS2C...

    This is both at server launch or trying through the Web Interface after the server is loaded...

    Now it might be a size limit issue maybe or a timeout etc.

    looking at Combat as an example:

    http://steamcommunity.com/sharedfiles/file...ls/?id=82684884

    The maps that have downloaded are all showing on SteamWorks as < 1.6MB

    The Co Core Alpha and Combat Mods are both over 2MB.

    Now while the small differences in size shouldn't make a difference.

    After many restarts of the server, I did once get the Co Core map to download, but the Combat has never downloaded for me.

    Co Core shows as: 2.888 MB
    Combat is: 5.816 MB

    So not sure if that is relevant but maybe if the NS2 Team look at it, it will be?

    As an update to this, Wireshark shows that the files are actually at least starting to download.

    UPDATED:
    I was looking through the TCP Streams and saw a lot of Checksum errors, I therefore to make sure it was not going to cause me any additional problems went into the Network Adapter and Disabled TCP Checksum Offloading which resolved those problems.

    I then went and did the Analysis below.

    After this I started getting a different error "download error 7". I wanted to see if this was different because of the Checksum changes, so I changed Checksum Offloading back and after I restarted the Server.exe quickly a few times both Combat and Co Core ended up downloading... So I am a bit lost.


    I can even see the zip file links and they download 100% file if I go to them directly through a web browser.

    My guess is that there is problems with the Server.exe methods of pulling these files? It obviously works in some circumstances but is not working on all.

    It looks like the TCP stream just ends prematurely? I am not a network expert so my analysis could be completely wrong but I see a bunch of packets related to the download but obviously the download is failing says the NS2 Server.exe.

    Could this be because they are killing off the thread before its finished? i.e. because it's taking too long or something?
  • RothgarRothgar Members Join Date: 2009-11-13 Member: 69372Posts: 228
    NS2C Still fails to download, with or without the TCP Checksum Offloading.

    It is quite a bit larger though at 19.9MB? This could actually be a problem with Server.exe timeouts maybe?

    So strange.
    Can a dev acknowledge this as an issue?
  • endarendar Members, Squad Five Blue Join Date: 2010-07-27 Member: 73256Posts: 620 Fully active user
    Checksum offload often shows up as an error in wireshark, but thats only because the network card has already done some work, and not told wireshark about it. It's often safe to ignore.
  • RothgarRothgar Members Join Date: 2009-11-13 Member: 69372Posts: 228
    Yeah there must be something wrong with the way the NS2 Server.exe downloads the files because if I look at the header information I can see the download file it's retrieving and as I said if I manually open a web browser and go to that link the zip file downloads no problems at all.

    The NS2 Modding system is a bit strange, I downloaded that zip file and extracted it to my mod folder, I used the mod ID and then _ and after that the last updated timestamp as it seems this is the syntax yet it still won't load NS2:C it keeps trying to download at startup.
  • RothgarRothgar Members Join Date: 2009-11-13 Member: 69372Posts: 228
    My mistake I forgot to put the "m" before the mod ID.

    The manually downloading the zip file and then extracting to the right folder works perfectly fine, so must be a bug with the Server.exe downloading.

    New version of combat:
    http://cloud.steampowered.com/ugc/54181947...19CA351DD34BF5/
    Folder name: m5f35045_1354654579

    I'm still not sure where I can get the timestamp from, apart from checking my clients workshop folder. Is anyone able to tell me what the latest timestamp is for the combat mod?

    edit: Thanks Jibrail, got the folder name.

    I'll get it tonight and add to my Server Guide.

    In the meantime for any people that are having mod download issues I have converged this into General Technical Support...

    http://www.unknownworlds.com/ns2/forums/in...howtopic=125561

    I am hoping one of these days if I post in enough places with descriptive detailing of the issue that UWE will acknowledge the problem and look into it.

    Have not seen any feedback and I expect this is probably because not enough people are screaming or posting their problem in these forums.

    As I have said before most people don't understand they have a problem because "Downloading Mods" is a VERY generic message and so they just quit and move to a different server not knowing there is an actual problem they should be reporting.

    Huh it is. Thats weird, I came home today and it had stopped working since "server mod is out of date". I didn't check the versions, thanks :P but redownloading it fixed it.

    I have tried countless times and Combat Mode (as well as one map) fails to download. All other combat maps download fine, not much use without Combat Mode.

    I find that it will almost always fail if you are trying to download more than 1 mod at the same time. I have yet to have it fail if I only load 1 mod at a time to download. Obviously this doesn't fix the problem, but it is a potential work around.

    It seems to also be dependent on the connection speed of the server. I have only tested with servers that have full 100 Mbps connections and I don't see too many problems. Slower connections are more likely to time out when trying to download larger files.
