I am working on an application in Xcode 6.1, iOS 8.1; the application was working completely fine till 2 days before, but today as I executed it I got an error in the web se
Ok, I lost a lot of time investigeting similar issue.
In my case the problem was strange (bad?) firewall on the server. It was banning device when there was many (not so many) requests in short period of time.
I believe you can do easy test if you are facing similar issue.
If you now got timeout for all next requests, you probably have same issue and you should talk
with sever guys.
PS: if you don't have access to server you can give user info that he should restart wifi on device to quit that timeout loop. It could be last resort in some cases.
