Hi, unfortunatly I encounter the following error. I don't have any clue which certificate is needed to be added. request to [https://epr.elastic.co/categories?kibana.version=8.9.0](https://epr.elastic.co/categories?kibana.version=8.9.0) failed, reason: self signed certificate in certificate chain Curl works perfectly: ubuntu@ip-:~$ curl [https://epr.elastic.co/categories?kibana.version=8.9.0](https://epr.elastic.co/categories?kibana.version=8.9.0) -I HTTP/1.1 200 Connection established Proxy-Agent: Fortinet-Proxy/1.0 HTTP/1.1 200 OK Date: Wed, 02 Aug 2023 14:16:19 GMT Content-Type: application/json Vary: Accept-Encoding Strict-Transport-Security: max-age=31536000; includeSubDomains Via: 1.1 google Transfer-Encoding: chunked Cache-Control: max-age=600,public Alt-Svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000 The server is located in AWS. Maybe thats a problem? Is there an option to ignore the validation? Thanks a lot in advance. 🙂 ---
