The bottom layer of the written client program uses libcurl to access the GAT1400 server, and occasionally the error code is 28 and the request timed out. How to intuitively notify third-party vendors to fix the problem
solution
https://elifulkerson.com/projects/tcping.php Download the tcping.exe tool, which can visually show whether the remote server port can be accessed and the access time for multiple accesses
The test results are as follows:
tcping.exe 192.168.10.89 8080
