Our user use App and receive some error code "Error Domain=NSPOSIXErrorDomain Code=49 "Can't assign requested address"",
I have search our monitor, find one user only appear one time and then could connect to our server again .
however another user cannot connect for a long time, each time it try connect to server (direct with socket) ,it receive this code (49), and http request NSURLConnection return -1004 error code . We have ask this user , he told us he also open WeChat at that time, it seems it also cannot connect to server.
We have already search google and cannot find a reason could answer this problem.
Could someone tells us which situation may cause this problem?
More Info:
User open our app when 08:15, then until 8:55, he open app again , and then the app raise these error code for a long time for many times.
