Sandbox not working?

I have the same issue.

I'm trying to connect to gateway.sandbox.push.apple.com:2195 over old tcp protocol. There are any ip addresses behind this dns-name.

When I trying to connect to concrete ip address (17.188.166.23б for example), connection broke with error "SSL handshake invalid certificate chain". But sometimes connection success for any ip address (but some time later broke again).

As I see, Apple has a problem with ssl-certificates.

I am also having the same issue and am using Azure Notification Hubs. I have done the following:

1. Created a new Development Push Certificate and tried to add the new certificate and a 400 Bad Request is returned

2. Created a brand new notification hub and attempted to add existing and new DEV push certificates and still get a 400 bad request

3. Sended a Test Notification with an existing and untouched notification hub that was working is rejected due to "invalid credentials"

Not sure what to do either, it seems like APNS Sandbox is currently not functioning.

same here. the certificate based push notifications in sandbox doesn't work. and I found lots of people from stack overflow facing the same problem these days.

Glad to see it's not just me. I've been wringing my hands that I might have screwed something up.

UPDATE: I attached a packet sniffer to my development machine and determined that the amount of data being returned from the sandbox server compared to the production server is vastly different. I don't know it that really means anything, but it seems to validate the concern that it's a problem with the sandbox server.

Interestingly we saw this yesterday with our sandbox account and as of today the same is happening on the produciton service.

This is troubling. My production is still working, so I hope it's not a widespread problem.

UPDATE:

My Sandbox notification hub is working now.

- The existing hub that was untouched is able to send notifications again.

- I was able to update a notificaton hub with a new sandbox certificate.

It's still not working for me.

I am not familiar with this issue but this might be relevant:

I am also having the same issue and am using Azure Notification Hubs.

- Uploading certificate in Sandbox environment gives error

- Whereasuploading to Production environment works fine

I solved this error with this property in ApnsConfiguration of my WCF service:

ApnsConfiguration configuration = new ApnsConfiguration(serverPush, appleCert, key);

configuration.SkipSsl = false;

There seems to be some progress. As of now, the system is at least not throwing a certificate error, but the iPhone app on the development device is not receiving the notification.

Edit: I no sooner posted this and tried again, and it came through. I think we are all clear now.

Hello,

I run into this problem too. Do you have any solution?

This problem has surfaced again in July and I think it's happening again today.
