Hey! I’m following the local installation guide in Litium Docs, and I’m encountering a `System.Runtime.InteropServices.SEHException` when adding the connection string to Elasticsearch in appsettings. Sometimes I get through but when I then try to rebuild my indexes the error pops up again. ![image](https://canada1.discourse-cdn.com/flex030/uploads/litium/original/1X/416be61bbfd85ff4bc806ca87277828ebe664326.png) I have tried to redo the configuration of the MVC Accelerator, tried different Elasticsearch versions and there are no signs of any errors in any of the logs. Any ideas? / Filip Litium version: _8.22.2_ ---

Update: It suddenly just started working. Not sure how or what the root cause was but glad it works now. ---
