IOS when calling a web service, the server with the specified host name was not found

Question

The random error I get when I try to call api

The following is a snippet from the error description.

NSLocalizedDescription = "A server with the specified hostname may not be found."; NSUnderlyingError = "Domain Error = kCFErrorDomainCFNetwork Code = -1003 \" A server with the specified host name could not be found. \ "

The error is very frequent, and it disappears on the next call. Can someone help me identify the root cause?

Answer 1

The error is due to the host not found.

kCFURLErrorCannotFindHost = -1003,
kCFURLErrorCannotFindHost
The connection failed because the host could not be found.

Maybe something is wrong with the DNS server, you need to ping the host and check if the host is accessible.
