I know that this problem may be api specified but really need to try.
I have to requests. One made with ASIHTTP and the other one with AFNetworking. Server denies afnetworking with 401 code.
I have to adjust afnetworking to the working state, and have in mind that changes at the server side are impossible atm.
ASIHTTP (working one)

AFNETWORKING (getting denied with 401)

There were some other headers but they were identical so I removed for simplicity. What could cause rejecting here? user-agent? Doubt that. What about Connection and Proxy-Connection? Can i change it to close in AFN?
401 is the HTTP status code "Unauthorized", which is sent back from the server when the provided credentials are invalid (incorrect username / password). Check that you're sending the correct information.
Also, JSON serialization is provided automatically when AFHTTPClient is configured correctly. See the example app in the AFNetworking repository to see how that is done.

Google Natural Language API has been working in my iOS app up until yesterday. The API started returning "permission denied" errors as of this morning. E.g:
{
"error": {
"code": 403,
"message": "The caller does not have permission",
"status": "PERMISSION_DENIED"
}
}
Example request:
POST /v1/documents:analyzeEntities?key=..... HTTP/1.1
Host: language.googleapis.com
Content-Type: application/json
Connection: keep-alive

Billing is enabled for the account (with a balance of $0). The account also has 36 days left on the trial period.
The key matches the value in the Google Cloud Platform API dashboard. I have also tried regenerating the key, and using the new key in the app.
I have also tried enabling key restrictions for iOS devices, and included the "X-Ios-Bundle-Identifier" header with the app bundle identifier.
The app also uses the Google Vision API which works without issues. Calls to the Vision API do respond to changes to the key restrictions.
Calls made from the demo page also show a permissions error message. Calls from the API explorer do work however.
Edit:
The error is also happening on the demo on the product web page. Tracing the error in Charles shows the same "permission denied" response being returned to the web page:
Edit:
Below is an example of the HTTP request and response captured from the demo page. The request and resulting error is almost identical to my app, except that the demo seems to be using http 2, whereas my app is using http 1.

We are aware of this issue and should be fixed now. Let us know if you still see the same problem.
I have experienced the same behaviour and I believe it is an undocumented change at Google's end.
I can now only make the call work via OAuth, despite the documentation suggesting that an API key is sufficient. Up until very recently it was possible to make a call with an API key only and no restrictions configured on the key.
My "answer" for what it's worth is to provide feedback on the documentation page to complain that the documentation doesn't match the behaviour. I think the wording on the page may have changed recently, but it still suggests an API key should work for testing purposes.
"TRY NATURAL LANGUAGE API" button from Google Cloud Vision API demo page doesn't work either! Looks like some bug, hope they fix it soon...
HTTP digest authentication no longer works in our app since iOS 10 due to wrong nonce-count in Authorization: Digest header generated by NSURLSession.
The same code works in iOS 9, but fail to auth in iOS 10
Create a POST request with NSURLRequest
Fire it with NSURLSession
Handle NSURLAuthenticationMethodHTTPDigest in urlSession(_:didReceive:completionHandler:) delegate
The server responds with a 401 and qop="auth" string as expected
The app requests again with the Authorization: Digest header set.
According to RFC2617:
nonce-count
This MUST be specified if a qop directive is sent (see above), and
MUST NOT be specified if the server did not send a qop directive in
the WWW-Authenticate header field. The nc-value is the hexadecimal
count of the number of requests (including the current request)
that the client has sent with the nonce value in this request. For
example, in the first request sent in response to a given nonce
value, the client sends "nc=00000001". The purpose of this
directive is to allow the server to detect request replays by
maintaining its own copy of this count - if the same nc-value is
seen twice, then the request is a replay. See the description
below of the construction of the request-digest value.
However, the nonce-count start at "nc=00000002" even for the first request in iOS 10, which cause the server to reject it.
Expect server response 200 OK

Is anyone facing the same issue?
The only related post I could find is:
Apple Developer Forums : Problem of the digest authentication, but no further information.
How do you fix it or get workaround on client app side without asking server side to ignore the wrong nonce-count?
Thanks.
Apple Developer Technical Support confirm that is a bug of iOS 10.
Hope it will be fixed soon.
Thank you for contacting Apple Developer Technical Support (DTS).
We believe this issue is a bug. Please file a bug report using the Bug Reporter tool https://developer.apple.com/bug-reporting/.
Update:
Apple fixed this issue in iOS 10.2 Beta 3
Chances are, the OS is sending a HEAD request first, and your server-side code isn't getting it. I would try running Charles Proxy to verify that this is what's happening.
That said, skipping a nonce count is not inherently an indication of any sort of attack. It could occur even in iOS 9 if a request got lost somehow (e.g. a network error). What's important is to ensure that the count doesn't go backwards. So I would argue that your server code is buggy and should not be rejecting that to begin with.
We have the same problem in our company as described here:
Cordova app can't connect with Dynamics NAV Web-Service (ODATA) after update to iOS 10
We can reproduce the issue both in our App and the Safari Browser with iOS 10 devices. There does not seem to be a simple client side workaround. We opened a Bug Report with Apple.
In our case the problem was solved with the 10.2 Beta release.
I was trying to integrate linkedIn oauth into my website, But I'm stuck on this error

I'm getting this error when i was trying to get the accessToken using authorization code.

I was follow the tutorial to make the request to obtain the response with token.But always get the error.

I'm trying to stream an audio file from a server protected by session-based authentication, and I've noticed that both MPMoviePlayerController and AVPlayerItem / AVPlayer do not appear to be using the cookies set in NSHTTPCookieStorage. If I make the same URL request using an NSURLConnection, I get a 200 and am able to access the audio file. When I monitor the requests through a proxy, it appears that MPMoviePlayerController does not set the cookie in the request header, while NSURLConnection does:
Request made with MPMoviePlayerController's initWithContentURL:
GET /path/on/server/test1.m4a HTTP/1.1

Does anyone know how to get MPMoviePlayerController or AVPlayerItem to use an NSHTTPCookie when requesting a remote resource?
You can intercept the request from MPMoviePlayerController using a class derived from NSURLProtocol and inject cookies along the way. Here's the code: https://stackoverflow.com/a/23261001/3547099
There is AFAIK no way to enforce cookies (or any other additional HTTP-parameters) when using MPMoviePlayerController on remote streams / files.
Maybe a GET-Parameter would be a possible workaround for your task?
