Hey folks,

i have created a new instance of bluespice.  
Afterwards the successful installation of Opensearch (V2.15) i ran the Script  
" php extensions/BlueSpiceExtendedSearch/maintenance/initBackends.php --quick "  
and this produces following Error :  
\ ***…vendor/opensearch-project/opensearch-php/src/OpenSearch/ConnectionPool/StaticNoPingConnectionPool.php: No alive nodes found in your cluster"**

But The Node is Alive and accessible :

```auto

There is no difference between the secure mode or not secure mode.

The Wiki SpecialPage SearchAdmin shows the same Error: **No alive nodes found in your cluster**

_System info:_\*

Hello and welcome to the BlueSpice community forums!

Looks like you are using an existing OpenSearch instance. You most likely need to configure the endpoint using the following variables:

```php
$GLOBALS['bsgESBackendHost'] = 'myhost';
$GLOBALS['bsgESBackendPort'] = '9002';
$GLOBALS['bsgESBackendTransport'] = 'https';
$GLOBALS['bsgESBackendUsername'] = '...';
$GLOBALS['bsgESBackendPassword'] = '...';

```

See also [Reference:BlueSpiceExtendedSearch - BlueSpice Wiki](https://en.wiki.bluespice.com/wiki/Reference:BlueSpiceExtendedSearch#Configuration)  
This can be done at the end of the `LocalSettings.php` file. Or if you are using the new “docker compose stack” in `${DATADIR}/wiki/bluespice/post-init-settings.php`
