Privacy and Security

I am not promoting the previous method anymore as there is now a secure way to connect to the game's server.
GitHub download link for my program that solves this is in the guide above.


It is confirmed that you can continue your old game progress and also achievements are unlockable again. I myself have already played a few matches with some new friends. Video proof by Guardian of Gotham:

Special thanks to Sazzouu for guiding me in the right direction.

I see some mistrust, skepticism, and confusion about this topic, so let me clear some things up.

Do not use simple HTTP connection on the internet if you can avoid it.

HTTP

If you genuinely and strongly care about your privacy then DO NOT use this method. But then again I hope you NEVER EVER visit a website that doesn't use HTTPS. You see the same thing is happening here as in any web browser.
I consider visiting a HTTP website even more dangerous than using it with this game because on websites you could potentially enter your username, password, etc. and on HTTP these are sent without encryption. In this game you don't enter any of your credentials. Only the game and the server itself are sending tickets, tokens, WBuserId, user stats, user inventory information, etc.
If you are not comfortable with these information being visible on the web, then DO NOT use this method. Sadly I don't have an alternative for you then.

How and why does this work? How can I confirm it?

It is very simple to confirm that the connection indeed works without even starting the game.
As I mentioned the connection works the same way as any connection to a website through a web browser. Based on this you can visit the address in question in Firefox (I don't know how other browsers handle this), this address: https://ozzypc-wbid.live.ws.fireteam.net/
You should get a warning from Firefox. (In the game this was the point where we got the ERROR 3 as we all know it well)
This Firefox warning in itself shows us the server is still up and running because if it wasn't then Firefox would simply show a "Server Not Found" message.
Now if you click on the "Advanced" button you can see the error code and even check the server certificate. If you view the certificate you can see at the Validity section this: "Not After: Wed, 19 Jul 2017 16:35:26 GMT". This is the exact time when the server was no longer accessible by the game.

However we can also check ourselves in Firefox if the http version is available or not. If you did you can see it works and gives you a "Permission Denied" page. (Probably because the server is set up to only communicate with the game properly.)
It works because HTTP doesn't require certificates but on the other hand this protocol does not encrypt the data traffic at all.

This means the server was never shut down, only the server certificate expired.

I can ensure you that at no point you ever share information that is severly sensitive
You basically share an OTP session token which at worst can be voided and therefore terminate your session with the online service and the second thing you share is you unique SteamID which is public anyways

What kind of help you need?

It already is playable as I have tested it yesterday with some friends
Only thing I need is people to fill my lobby for those freaking full lobby achievements

I will check if its safe to connect first

As I said earlier the only thing that is shared is something that at worst terminates your current session if abused.

EDIT:
You are not sharing any sensitive data at all.

Yes, you heard (read?) it right. We can still play the Online mode.

I have accidentaly discovered this while trying to make Online work based on Sazzouu's idea with his help.

And it is absurdly easy to make it work.

:tyger:
However I feel obligated to warn you, that this method uses an insecure connection to the server thus the communication with the server will be visible and could be easily hackable on the web. I didn't find any sensitive information in the traffic while testing but I also don't understand every single data that gets sent. So if I'm mistaken then you have been warned about the risks.
:tyger:

I did some minimal in-game testing and I have to tell you not everything works flawlessly but at least the overall gameplay works. You can host and join lobbies and that's what really matters.

It is now confirmed that you can get back your old game state / save and also achievements are unlockable again. I myself have already played a few matches with some new friends. Video proof by Guardian of Gotham:

To get to the point, the details of the fix can be read in my guide.

Initially when I was just testing I had a problem of Arkham Credits not saving after the match ended. This seems to be okay now that I played with multiple people.

The only big problem I see now is in the lobby system. Right now the host cannot continue the game in the same lobby, because the game hangs for everyone else on the loading screen if they continue. The host has to exit the lobby and someone else has to invite them back. This changes the host every time and it is a little bit uncomfortable to go through all this after every match but that's what we got.

If you thought I meant there are problems with the server connection, I can assure you there is nothing wrong with the connection itself.

Thanks for your response. So it basically means game works :D
