I have solr 7.5 working and am able to hit secured admin panel https://solr75:8983.
My connection string settings in index worker and site root are set to https://solr75:8983, my hosts file has an entry for solr -127.0.0.1 solr75 - but I still get this error:
An error occurred. System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:8983
I am able to hit my xconnect instance with no errors, SSL thumbprints match. The SSL certificates when I hit https://solr75:8983 are valid and trusted. I don't see 127.0.0.1:8983 entry anywhere. Why is it looking for 127.0.0.1:8983?
