Hi Experts-
After connecting our TREX installation (7.1 Rev 57) to a ABAP (Netweaver 7.4) system, we are seeing errors while performing ICM Connection Tests. Here is the error-
Connection Test failed. HTTP Status 401: Kernel error:ICM_HTTP_CONNECTION_BROKEN (401 )
The RFC connection test works fine and the issue is only with ICM test. Any help here to pin point the error will be appreciated.

Hi Amit,
I suppose that the issue is caused by the wrong settings in the TREXADMIN . Could you please check what are the communication methods activated in tc. TREXADMIN - TREX ABAP Customizing . If the TCM method is selected , please switch this to ICM/TCM and save the changes. The similar issue is described in the note 1967609. If it doesn't help could you please open OSS message for this problem .
Best regards,
Mikhail
Hi Amit
From Trex admin tool to back end system connection are correct?
could you refer the SCN link to cross check the configuration part from Trex admin tool

Hi Mikhail-
Here is the OSS number - Error with ICM Connection Test (Kernel Error): 401 ( 572535 / 2014 )
Thanks

Hi Amit,
Can you please repeat test TREXAdminTool (python) -> Connectivity ->connect AdminTool -> switch to ICM tab -> use IP instead of TREX hostname and create a new one screenshot. I suppose that the ICM is failed due to incorrect settings on the ICM side. Is the profile parameter icm/host_name_full set by you?
Best regards,
Mikhail
Hi Amit,
as the R/3 connection doesn't work (timeout error from saprouter) I can not logon into the system . Could you please check it. Could you please also put in the OSS message the entry from the profile file - what's set for icm/host_name_full parameter. It could be possible that you put FQDN of a server (or different one server) , this can not be resolved and the HTTP Service can not be started correctly due of this.
Thanks,
Mikhail
Hi Mikhail-
I have replied to your queries in the OSS message. Additionally, since we are getting 401, it has to do with some sort of Authorization error.
I also checked by tracing in wireshark, the connection gets terminated (RESET) after the initial handshake between AS/ABAP and TREX Engine succeeds.

Hi Amit
1. Just check with SAP Notes
1246275 - BIA 7.00 & TREX 7.00: ICM connection test fails
1967609 - TREX 710. Indexing failed with error "could not load DBSL library"

Hi Mikail-
We were able to fix the problem after working with network team. Even though we were able to telnet back and forth between SAP Application Server and SAP TREX server, still we needed to define some explicit firewall rules with the help of network team in our landscape.
Thanks a lot for your help and suggestions.

Hello Amit,
WE are also facing same issue with the trex server. From your experience I understand that your network team did some changes in the firewall. Same I want to suggest to my team as well. So could you please brief me about these changes to be done at n/w.
Thanks a lot in advance,
Bhaskar
