I have a PHP website on a linux server.
I am using nusoap function from nusphere website for connecting to a eservice gateway.
I had no problem for a few months with it, but recently i got the following error.
Error: wsdl error: Getting https://www.something.com:27635/eservice.asmx?wsdl - HTTP ERROR: cURL ERROR: 7: couldn't connect to host
I contacted to my linux host server and ask them for telnet the address and the port 27635. and below is the result
root@ns3 [~]# telnet www.something.com 27635
Trying 212.80.nn.nn...
Connected to www.something.com (212.80.nn.nn).

root@ns3 [~]# wget https://www.something.com:27635

It seems the connection is ok.
Many Thanks.
Finally! i found the solution.
A few weeks ago i changed some of my PHP programs for using gzip compression.
I had inserted ob_start("ob_gzhandler") at the start of the programs, but i had forgotten to put ob_flush() at the end of them.
So there was some nested output buffering.
There was no problem with all programs except than my WSDL eservice program which uses CURL.
It generated curl error 7 or 28.
