    So as we know, one can't load the game's website through IE11 on Win7, effectively making the client the only possibility to launch the game for a group of users. IE11 still works on Win10 however.

    And here's the cause: Newer cipher suites are now required (particularily TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256), ones that are in Win7 and not in Win10. Other browsers work because they're not using the OS preinstalled ones, but their own lists instead. Since the preinstalled OS cipher suites can't be changed (as far as I know), IE11/Win7 simply can't afford the currently required cipher suite. Probably the same is the case for IE11/Win8 and IE11/Win8.1.

    So, here's a question to be forwarded to the devs:
    Could the TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 and/or TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 cipher suites be enabled server-side for IE11/Win7 compatibility? Those two are quite safe too.

    That is not possible - the server's certificate provides RSA key so only RSA can be used for authentication (EC can't).
    I guess the "easiest" solution to this problem would be to enable following cipher suite (at least one of them):
    • TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 (0x9f) DH 2048 bits FS
    • TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 (0x9e) DH 2048 bits FS

    No but TLS_CHUCK_NOR_RIS_WITH_ROUND_HOUSE_KICK_256_INF_POW is already enabled ;)
    Sorry for the late response dude :) ... I haven't been playing much lately and I was not visiting the forum.
    BUT ... I have news for you :)
    I "hacked" the browser and I was able to play the game in browser on Windows 7 (I am not stupid to install spyware 10).
    Not just that ... I was bored so I have done a small challenge. Now , I can play the game not just in IE11 but in Firefox too :p
    Actually Firefox is much better. :D

    This is a full screenshot so you can see the Browser and the OS ... and the date and the game version.

    So I understand that you first got IE11/Win7 to work, but then also got Firefox to work? So how did you do it exactly?

    I mean, Firefox actually seems easier than IE to get it to work (and I actually managed to do it).

    Very easy, instead of making things complicated I made them simple :) because things are almost always simple but we take them in a wrong way.
    Instead of searching for dev's help I have relied on my own experience.
    Instead of messing around with encryption and certificates I used something that is already working on its own (Firefox) without relying on the OS and its updates.
    Instead of using IE, which is Windows dependent, I did use Firefox and made it trick the game's website thinking it is something that it is actually not :D
    Making IE11 work in Seven is complicated but making Firefox work is easy ... all you have to do is "brainwash" the Firefox. Convince the browser its name is not Firefox but Internet Explorer and it is not running on Seven but on Spyware 10, so when the browser meets the game's homepage later, their conversation would be like:

    Firefox: Hello DSO Homepage
    DSO Homepage: Hello Browser
    - handshake -
    DSO Homepage: who are you?
    Firefox: My name is Internet Explorer 11
    DSO Homepage: Where are you from?
    Firefox: I live in Spyware 10
    DSO Homepage: OK, you may pass ... one more thing ... can you run Java?
    Firefox: Yep ... Java is my middle name
    DSO Homepage: Fly with the wind my friend ... there you go, I will enable the "play now" button for you
    - Firefox starting the game -

    In short - the game thinks i am using Internet Explorer 11 on Spyware 10 ... but i am not :D
    It is very easy process, there is nothing illegal and I could make a Wiki guide for it ;)

    Well, that I had figured out myself already. I thought that you had a way for IE11 which I couldn't think of (and of course don't need). However, I used IE11/Win7 user agent... and yes, it all works.

    Could it be possible to use firefox in Linux to play like this?

    Why would I use IE if I can do the same with FF? Until now I was using IE because it was running the game without doing any extra stuff ... but now when I need workarounds to make the game working ... I don't need IE11. IE is crappiest browser (still better than the client) no point using it now.
    The user-agent is not an issue ... the trickiest part with Firefox is to make Java work with it.
    I know you know what I am talking about ... but I am keeping the details for the guide XD

    I am still a noob for Linux ... but using logic I would assume it won't work unless you run it on Wine.
    The game is not made to be working on Linux, it has been coded and engineered to be working on Windows.
    Try running it on Wine with Firefox. You can probably run the client on Wine too ... but browser has a lot of advantages over the client, especially when the client is not working and the CDN is screwed up.

    On the other side, client should be UDP vs browser's TCP

    Browser is using some UDP too.
     
  13. trakilaki

    trakilaki Living Forum Legend

    Not really true :p
    Games are using UDP ... but the Java container is environment on its own it is browser independent that is why the game is running in the Java container which is acting like a client, so it must be combined usage.

    Here is the guide on how to run the game in Firefox and Windows 7. :)
