ENOTCONN when verifying password reset code

[Aaron Sullivan]

Hello,

I'm building password reset functionality for our iOS app. What I would like to do is when the user clicks the link in their email, the app opens to a password reset screen that validates the code.

Currently I have the %LINK% customized as a universal link for my domain, and most times this is working:

1. User clicks link

2. Since it's a universal link, iOS hands it to our app via "continue userActivity"

3. Link is parsed for oobCode, and handed off to password reset screen

4. When the screen receives this code, it calls verifyPasswordResetCode to check the validity.

However, sometimes I'm receiving the following error (logged in console):

Error Domain=FIRAuthErrorDomain Code=17020 "Network error (such as timeout, interrupted connection or unreachable host) has occurred." UserInfo={error_name=ERROR_NETWORK_REQUEST_FAILED, NSLocalizedDescription=Network error (such as timeout, interrupted connection or unreachable host) has occurred., NSUnderlyingError=0x106f9ee00 {Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

A sample of the console debug logging during this time:
