We use iOS chilkat socket library for iOS project. We use c++ api for our needs. We have an issue with "Connect" (without ssl) method. It always return true. Even if server is not running. (BTW on windows project it works as expected.) When we try to read something from this socket (on iOS side) with the usage of method "ReceiveBytesN" it returns false. get_IsConnected() function returns false and last error is:

I used the lates version of library (9.4.0). Result is the same. I'll try to use VerboseLogging and and LastErrorText after connect. Then I'll give an update here.
Computer with destination IP is powered off.
Here is updated log from LastErrorText after calling function Connect:

The information in the LastErrorText shows that the connect system call succeeded. (see http://linux.die.net/man/2/connect ) I don't have any other answer.
Found out some new information. When computer, where Server is installed, is off socket's function "connect" works as expected. (after timeout returns false)
