SSL Error -1200 on Low Network Signal with Airtel

Description: I'm encountering an SSL error (error code: -1200) when trying to establish a secure connection in my app. This issue only occurs when the network signal is low on Airtel. The connection works fine on a normal network signal.

Here are the details:

  • Device: iPhone 11
  • iOS Version: 17.2.1
  • Network Provider: Airtel
  • Error Message: An SSL error has occurred and a secure connection to the server cannot be made. Error code: -1200

Tried different network settings and Observed the issue only on low network signal.

Any insights or suggestions to resolve this issue would be greatly appreciated. Thank you!

Error -1200 is NSURLErrorSecureConnectionFailed, which is very generic. There’s usually an underlying error, in the -98xx range, that reveals more info.

It’s quite possible that this error is natural fallout from low signal, that is, something got dropped and that triggered a chain of errors that resulted in this very generic error code. OTOH, it’s also posible that something about this low-signal environment is causing the carrier to munge packets [1]. Regardless, an RVI packet trace should reveal what’s failing on the ‘wire’.

[1] It’s not like carriers don’t have form when it comes to this sort of thing.
