PushSharp.Apple.ApnsConnectionException: SSL Stream Failed to Authenticate as Client

[raheem52]

I am using PushSharp 4.0.10

When I am trying to send iOS notification.

I receive below error

Send Batch Error: Batch ID=1, Error=PushSharp.Apple.ApnsConnectionException: SSL Stream Failed to Authenticate as Client ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception. ---> Interop+AppleCrypto+SslException: bad protocol version8

@raheem52 seeing same this morning too. Had some push notifications go out but occasionally getting this exception.

[MostafaSholkany]

Same error withe me

[Sebastian506563]

Same here,

1. Tested only locally
2. Started to fail after update to Windows 10.
3. First notification after running always fails, next are fine.
   I am guessing something wrong with Tls1.0

[sevafeld]

Same here

Just updated my code to force TLS 1.2 and waiting to see if this error shows up again.

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

[dannycabrera]

No errors in about 4 hours so this might have done the trick. Thanks @Sebastian506563 for pointing out TLS issue.

@dannycabrera where did you put that? I'm having the same issue, just put that line before apnsBroker.Start() and it's still failing for me...

Usually this should put in your Application_Start method but this depends on your architecture of course.

[dannycabrera]

Thanks @sonergonul. Exactly where I placed it, right before any PushSharp initializing.

[jlubeck]

Doing just that didn't fix it for me. I had to run this on the recommended settings to fix the Ciphers on my computer as well: https://www.nartac.com/Products/IISCrypto

[dannycabrera]

@jlubeck curious, what OS are you running PushSharp on?

[jlubeck]

@dannycabrera Windows Server 2012

Is there a chance anyone will update the nuget package to include the TLS fix?

[harvey-green]

I had this same issue, so checked out the master branch and built the project locally. Then included the references to the required DLLs (Apple and Core) manually into my project. The NuGet package for PushSharp is 3 years old and so does not include the required fixes for TLS 1.2.

[harvey-green]

By the way I was doing sandbox Apple VoIP push notifications via

gateway.sandbox.push.apple.com - port 2195

feedback.sandbox.push.apple.com - port 2196

They started failing on 23 July. Prior to that they were working fine with the NuGet package.

oh my god, it has taking my two days.

love you so much

The last two links are references to the updated PushSharp nuget. I'm not sure if the original author is trying to monentize PushSharp or if its a branch of someone else's. I ran the nuget packages and got past the current set of Tls errors related to Apple updates. Hope this helps folks.
