Got above error When I am firing api using AFNetworking. I have configured "App Transport Security setting" to allow arbitrary loads. Increased timeout interval of AFNetworking request serializer to 100 seconds. But none helped.

If you are testing on simulator you might face this issue. I guess the simulator internally may not able to connect to the internet, so that is why it was not able to connect to the server. Try restarting the simulator and check .If it still doesn't work correctly then clear all the content and data for simulator from Hardware --> Erase All Content and Settings.

If you are checking in the real device please check the internet connection of the device.

If the internet connection is working fine then there is some configuration to be done at server end with 'Keep-Alive' value in configuration. I found the same solution at multiple references as below :

Hope this helps.
