I took  jaytrixz s answer comment one step further and added  text html  to the existing set of types   That way when they fix it on the server side to  application json  or  text json  I claim it ll work seamlessly     manager responseSerializer acceptableContentTypes    manager responseSerializer acceptableContentTypes setByAddingObject   text html

This means that your server is sending  text html  instead of the already supported types  My solution was to add  text html  to acceptableContentTypes set in AFURLResponseSerialization class  Just search for  acceptableContentTypes  and add   text html  to the set manually   Of course  the ideal solution is to change the type sent from the server  but for that you will have to talk with the server team

A simple way to enable to receive  text plain  content type   manager responseSerializer acceptableContentTypes    NSSet setWithObject   text plain      Similarly if you wish to enable  text html  content type   manager responseSerializer acceptableContentTypes    NSSet setWithObject   text html

I had a somehow similar problem working with AFNetworking from a Swift codebase so I m just leaving this here in the remote case someone is as unlucky as me having to work in such a setup  If you are  I feel you buddy  stay strong   The operation was failing due to  unacceptable content-type   despite me actually setting the acceptableContentTypes with a Set containing the content type value in question   The solution for me was to tweak the Swift code to be more Objective-C friendly  I guess   serializer acceptableContentTypes   NSSet array    application xml    text xml    text plain    as Set lt NSObject gt

I solve this problem from a different perspective    I think if the server sends JSON data with Content-Type  text html header  It doesn t mean the server guy intended to send you some html but accidentally changed to JSON  It does mean the server guy just doesn t care about what the Content-Type header is  So if the server guy doesn t care as the client side you better ignore the Content-Type header as well  To ignore the Content-Type header check in AFNetworking   manager responseSerializer acceptableContentTypes   nil    In this way the AFJSONResponseSerializer  the default one  will serialize the JSON data without checking Content-Type in response header

On the server side  I added    header  Content-type  application json      into my  php code and this also fixed the problem

Setting my RequestOperationManager Response Serializer to HTTPResponseSerializer fixed the issue   Objective-C  manager responseSerializer    AFHTTPResponseSerializer serializer     Swift  manager responseSerializer   AFHTTPResponseSerializer     Making this change means I don t need to add acceptableContentTypes to every request I make
