NSURLConnection finished with error - code -1022

I think it is about App Transport Security.Because your url is not https.Try to change like this in the info.plist file

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

You are getting this error because you are not using https url. To fix follow below steps:

Add below line just before /dict:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

I was having a similar issue,

NSURLConnection finished with error - code -1200

I was trying to reach a blocked port in my company. Changing the port let me connect normally.

As pointed out below, disabling Firewall could also solve the issue.
