TIC Read Status [6: 0x0]: 1:57 Xcode 9 - Network Requests Not Working

Question

I try to make standard Https calls on a web server and very often get TIC Read Status [6: 0x0]: 1:57, and this interferes with web services. Does anyone else have this problem?

Answer 1

Error reading TIC [476: 0x60800018dc30]: 1:57

Ok, here's how it breaks:

• "TIC" expands to "TCP I / O connection", which is a subsystem in CFNetwork that starts a TCP connection.
• The "reading error" is pretty clear.
• "476" is the connection identifier in the TIC; its not good for us
• "0x60800018dc30" is a pointer to the TIC object itself; again its not good for us
• "1" "57" - CFStreamError ; 1 kCFStreamErrorDomainPOSIX, 57 ENOTCONN

, TCP ENOTCONN.

TCP I/O API, (, NSURLSession). API ? ? , ?
