solr admin page connection refused after upgrading to 9.5.0 and sap cx to 2211.27

[superpalmi]

Hi,

I recently upgraded my Local Sap Commerce Cloud version from 2211.21 to 2211.27 and consequently had to upgrade my local solr configuration to 9.5.0 following this kba https://me.sap.com/notes/0003424311 and upgraded the configurations in this page and this page.  Now indexes and facets seems work correctly but i still cannot access to https://localhost:8983/solr/#/login anymore, as Chrome returns me ERR_CONNECTION_CLOSED error (I also tried with other browsers) without opening the page. It seems like my local instance is not running but when I try to curl my login form  curl http://localhost:8983/solr/ I get an html page stating this:

SolrCore Initialization Failures

• core: error

This is my output for

Maybe i mismatched the exact installation directory or something about security.json? Do you know what is the problem? Please note that I'm using windows 11 with WSL.

Thank you for your time.

Have you tried deleting existing indexes from Solr and running a full indexing via Backoffice?

[ChrisAr]

This has been a problem for some time. Not just since 2211.27 or solr version 9.5.0.
After much trial and error, my colleagues and I decided to install a browser directly in the WSL in order to access solr directly from there.

This happens because solr only allows access from 127.0.0.1 (its own machine), where your case, you installed it on WSL and tried to access it from Windows, so it counts as remote access.

to resolve this, I usually just edit the bin/solr file (for Linux), and add these lines on top:

SOLR_HOST=0.0.0.0
SOLR_JETTY_HOST=0.0.0.0

 After that, you just need to restart the solr and it will be able to be accessed from Windows.

[ChrisAr · Accepted solution]

Thank you. That worked for me.

In my case, I had to edit the file under the following path:

sap-commerce\core-customize\hybris\bin\modules\search-and-navigation\solrserver\resources\solr\9.5\server\bin\solr.in.sh

this worked for me too, thank you!

We also faced this issue exclusively with windows machine.

We also faced this issue exclusively with windows machine. We were accessing the ubuntu remote dev box from windows which was blocking the solr service. Got Fixed by above changes.
