UPDATED - Betfair.com Login - Disabling TLS Ciphers - 3rd February 2020

[aron]

Hey thanks MV, all good now!

[MV6man]

Hey Aron, I got mine to work (I'm running a NET version with TLS 1.2 btw) by inserting the line from the previous page so try:



Dim postData AsString = _

"username=" & My.Settings.Betfair_LOGIN & "&password=" & My.Settings.Betfair_PASS

Dim cert AsNewX509Certificate2(My.Settings.FilePath_DB & "client-2048.p12", "")

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

Dim request AsHttpWebRequest = _

WebRequest.Create("https://identitysso-cert.betfair.com/api/certlogin")

request.Method = "POST"

request.ContentType = "application/x-www-form-urlencoded"

request.Headers.Add("X-Application: " & My.Settings.Betfair_APPKEY)

My code...

Dim postData AsString = _

"username=" & My.Settings.Betfair_LOGIN & "&password=" & My.Settings.Betfair_PASS

Dim cert AsNewX509Certificate2(My.Settings.FilePath_DB & "client-2048.p12", "")

Dim request AsHttpWebRequest = _

WebRequest.Create("https://identitysso-cert.betfair.com/api/certlogin")

request.Method = "POST"

request.ContentType = "application/x-www-form-urlencoded"

request.Headers.Add("X-Application: " & My.Settings.Betfair_APPKEY)

request.ClientCertificates.Add(cert)

request.Accept = "application/json"

Using dataStream AsStream = request.GetRequestStream()

Using writer AsNew _

StreamWriter(dataStream, Encoding.[Default])

writer.Write(postData)

EndUsing

EndUsing

… doesn't work. Please help

I wont be able to fix this for 2 weeks now judging by the solutions posted elsewhere, I need physical access to the machine to make offline changes, absolutely fing furious.

Ive been running the same system forever without a hint of a problem, why were these changes made now?

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

It didn't work for me I already updated .net framerwork to 4.6 and tls 1.2 is available now but it has the same behavior.
I'm using windows server 2008 r2.
Is this a problem? How can I check which protocol is being used? I can login easily with curl.
Some help much appreciated

Thanks Zeal, the code

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

worked for me!

ReImage VPS server 2012!!! It works! Thank you

net 4.8 and server 2012

everything is correct in the program code. The bot works on another PC (win 2010). Stopped working on win server 2012 !!!

I would say that you need to make sure you have the latest version of .net (4.5 or over at least)

I am not the expert you need, but I can tell what I have done to fix my program.

I am using the betfair c# program i have found on the github. (Of course, I have modified it.)
There is a file as: AppKeyAndSessionProvider.cs. I have inserted this line before the login details:

try
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
string uri = string.Format("https://{0}/api/login?username={1}&password={2}", _host, _username, _password);

HttpWebRequest loginRequest = (HttpWebRequest)WebRequest.Create(uri);
loginRequest.Headers.Add("X-Application", _appkey);
loginRequest.Accept = "application/json";
etc...

Now the login was fine, but the BetfairClient.cs was throwing new errors, so I copy-pasted this line one more time:

public BetfairClient(string appKey, Action preNetworkRequest = null, WebProxy proxy = null)
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
if (string.IsNullOrWhiteSpace(appKey)) throw new ArgumentException("appKey");

this.appKey = appKey;
this.preNetworkRequest = preNetworkRequest;
this.proxy = proxy;
}
etc...

End that's it. Works like a charm.
Not the most precise solution, but I hope it can help you.

Hi Thurfe!

Thank you for your answer! It works.

My bots also failed to login today via the api on their windows 2008 server machine, but they would run on my win 10 dev machine.

I found the information above on what had changed to be particularly opaque, as I suspect very few bot authors would be explicitly choosing TLS ciphers.
I could log in to the betfair website on the same machine so concluded it was some config level thing rather than an installation level issue.
After some reading on TLS and default version behaviours on various operating system versions, I tried setting the TLS version in my code to 1.2 (rather than the default), and this seems to have resolved my problem, for now at least.

My fix, in C#, was simply: ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
