Direct connect to xxxxxxxxxxxxxxxxxxxx:443 failed: NIECONN_REFUSED(-10)

Hello Community,

I have an issue that I have been looking for a solution but with no luck.
I made a report to send HTTP GET request to some websites, so it worked and i got return code 200, and also the html content of the page.

Then I put the same websites in an internal table, so my report will run in a job and send a GET request to each one of them, Then I got a dump on my job.

The return message is : Direct connect to domaine:443 failed: NIECONN_REFUSED(-10)

What make me crazy is that it was working and I didn't change anything then, so why it would stop working like that !!

I tried a lot of things :
1- I imported the certification of the websites to STRUST : Helped me to get the report work in the beginning
2- Check the log 2 in smicm , below some line of errors that I get , but i really don't know how to understand them :
<<- ERROR: SapSSLSessionStartNB(sssl_hdl=7f69b40275d0)==SSSLERR_ALERT_CERTIFICATE_UNKNOWN

SapSSLErrorName()==SSSLERR_ALERT_CERTIFICATE_UNKNOWN

[Thr 140092513355520] *** ERROR => IcmConnInitServerSSL: SapSSLSessionStartNB returned (-127): SSSLERR_ALERT_CERTIFICATE_UNKNOWN [icxxconn.c 3145]

HttpPlugInGetErrorText: Return ICM client error ccccccc for ICM error Connection refused(-41)

HTTP/1.0 404 Connection Refused. Server: SAP NetWeaver Application Server..Connection: close..SAP-ICMCLNTERROR: 411..

Another issue , is that now in the smicm-> go to-> services, I can't make the https port activ ? Could any one help me with that !!

Thank you for your help

Hi Hicham,

the error NIECONN_REFUSED comes from the TCP/IT layer of the operating system and means that the hostname was accessible, but no one on that host is listening on port 443.

So it looks like the webserver that was previously running on port 443, is now shut down or something.

One point that is still unclear to me: from your question it seems that the ABAP side is HTTP client here (you are calling an external website using CL_HTTP_CLIENT, i.e. outbound direction). But then in your question you have a screenshot of SMICM, which shows the open ports of the ABAP system, so that would mean, the ABAP system is the HTTP server (inbound direction)?! If you are trying to be HTTP client, then SMICM has nothing to do with your current scenario.

Best Regards, Ulrich
