Retain version 4.11.0.1. After changing the commercial certificate for the Retain server and updating the worker bootstrap the server is up-and-running. But the indexes do not work.

Server configuration page is very slow in loading and the Index tab shows an error:

Error: An exception occurred processing [Manager/solr_config.jsp] at line [156] 153: String disableRefreshIndexConf = ""; 154: %&gt; 155: 156: &lt;%if(stateInfo.errorOccured() || Service.hasLength(stateInfo.getMessage())) { 157: %&gt;&lt;p &lt;%=stateInfo.errorOccured() ? "style=\"color:#FF0000\"" : ""%&gt;&gt;Msg: &lt;%=com.gwava.security.EncoderI.getEncoder().forHtml(stateInfo.getMessage()) %&gt;&lt;/p&gt;&lt;% 158: } 159: %&gt; Stacktrace: <br>Code: 500 <br>URI: /RetainServer/Manager/config.jsp <br>Time: Wed Aug 09 14:28:35 CEST 2023

The indexer logs show the following lines:

SolrClientNodeStateProvider$ClientSnitchCtx: Error on getting remote info, trying again: IOException occurred when talking to server at: https://localhost:8082/hpi

So I expect that solr is not aware of the new certificate and does not trust it. How can I make it trust the certificate? Or is there another reason?

When I do a wget on the https://localhost:8082/hpi I get a failed/Connection refused.
