Crawl Timeout 
The smoke test was unsuccessful due to a crawl timeout.
This may be due to incorrect TREX proxy settings.
Check the TREX proxy settings:
Log on to the blade where the TREX central instance is installed with the <sapsid>adm user and open a shell.
Make sure that X11 forwarding is enabled.
Change to the TREX installation directory:
cd <TREX_DIR>
Start the TREX admin tool with the following command:
./TREXAdmin.sh
In the TREX admin tool, navigate to the Preprocessor: Admin screen.
On the Proxy Settings tab page, check that the following settings are correct for your environment:
Proxy Server – host name and domain of the proxy server
Example
proxy.mylocation.mycompany.com
Proxy Server Port – port of the proxy server
Example
8080
Proxy User – user name needed to access the proxy server
Proxy User Password – password defined for the user
Proxy Exclusions – enter domains you want to exclude from crawling
Caution
Do not use an asterisk* at the beginning of an exclusion entry.
Note
For crawling, Proxy Exclusions should be set for all internal URLs, as otherwise the HTTP request may try to use the proxy and not be able to resolve the host.
Save the changes.
