Hello community,
I have a simple scenario where the Web Dispatcher should forward incoming HTTP/HTTPS call to a HTTPS endpoint on external system.
I have tried to setup the demo scenario just by defining the system as follows:
wdisp/system_0 = SID=EXT, EXTSRV=https://www.google.com, SRCSRV=*:443
Now when I connect to the web dispatcher via HTTPS/443 I get 500 Dispatching Error:
Error: | -26 |
Version: | 7400 |
Component: | HTTP_ROUTE |
Date/Time: | Wed Oct 28 14:55:54 2015 |
Module: | http_route.c |
Line: | 3448 |
Server: | wdf-ci-disp_WD1_00 |
Error Tag: | {0000009d} |
Detail: | no valid destination server available for '!ALL' rc=4 |
I have read that HTTPS to external systems was not possible in earlier Kernels so we did an upgrade and not the Kernel is 740, Patch Number 42 and the issue still persists.
The complete profile is as follows:
SAPSYSTEMNAME = WD1
SAPGLOBALHOST = webdispatcher
SAPSYSTEM = 00
INSTANCE_NAME = W00
DIR_CT_RUN = $(DIR_EXE_ROOT)\$(OS_UNICODE)\NTAMD64

Hoping for some advice,

Hello Ilja,
What is the content of the web dispatcher trace file?
Can it access the SAP system?

Hello Cristiano,
I see the following entries in Web Dispatcher:

Hello Ilja,
Could you check the SAP Help and see whether the configuration is ok?
From similar cases, be sure that is/HTTP/default_root_hdl = abap is not set.

Cris
