Domain=NSURLErrorDomain Code 1202

Question

Hi I receive the following error:

Error Domain=NSURLErrorDomain Code=-1202 \"The certificate for this server is invalid. You might be connecting to a server that is pretending to be “server-prod.name-cloud.com” which could put your confidential information at risk.\" UserInfo={NSErrorFailingURLStringKey=https://server-prod.name-cloud.com /v3/project/session/926B9E6BE31B/, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, NSErrorFailingURLKey=https://server-prod.name-cloud.com /v3/project/session/926B9E6BE31B/, _kCFStreamErrorCodeKey=-9843, NSLocalizedDescription=The certificate for this server is invalid. You might be connecting to a server that is pretending to be “server-prod.name-cloud.com” which could put your confidential information at risk.}

I read all the relevant docs, we apply all the requirements in "Common Failures" section.

More details:

• the errors received only from Germany(except 4 times in the past 2W that was from Italy)
• It is not reproducible in house
• Eventually after tons of retries the uploads go throw
• This was received booth in iOS 10.x.x & 9.x.x
• I use amazon servers with 2016-08 SSL Security Policies, so according to apple it should be OK

In the app I use:

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

note - in production I always use HTTP’s, I leave the NSAllowsArbitraryLoads because some testers offshore can switch the rout to HTTP for debugging.

Answer 1

If you're on a work laptop with any kind of security measures, the SSL certs may be getting inspected / MITM'd by the endpoint protection.

Try opening any web page in mobile Safari. I get these same NSURLErrorDomain Code=-1202 errors there as I do for https API requests from Xcode in iOS Simulator.

Solution will be to turn off this security feature...

Or install a certificate: https://developer.apple.com/library/archive/qa/qa1948/_index.html

Similar issue is asked here: iOS Simulator not works on https, all https are evaluated as not trusted

Answer 2

For the devs who are working with a server locally and need to get the iOS Simulator to trust the certificate. Follow the steps below:

1. Get the .cer file by exporting the certificate from the Keychain. You need the certificate file in a valid format and its easiest to get this by exporting it from the Keychain.

2. Drag and drop the aforementioned .cer file onto the simulator. It should give you a prompt on installing a "Profile". Go ahead and follow the instructions to install it.

3. For those who are working with the latest versions of Xcode and iOS Simulator. You need to do 1 last step. The Simulator must be explicitly told to trust the root CA. Do this by going to General -> About -> Certificate Trust Settings -> "Enable Full Trust for Root Certificate" for your particular certificate

Hopefully, this saves headaches for some people!

Answer 3

It took a lot of time for me to find a fix for this:

If any of us ran across the certificate issue,. It is because of antivirus preventing iPhone simulator to browse any websites.I was able to fix this issue by the following steps:

1. uninstall or turn off Antivirus in Mac.
2. erase all content and settings of simulator.
3. restart mac.
