Greetings, Apache Solr community. I'm here to ask for your help and advice about a Solr-related problem I'm having.
My company is an e-commerce website and uses Solr in production for the querying of items in our inventory. The Solr installation was done by an engineer who has left the company. About 2 weeks ago, Solr stopped working completely (our website wasn't rendering completely and we lost the search functionality). We also couldn't access the Solr dashboard, located in our server at [https://api.ishippo.com:8282/solr/#](https://api.mydomain.com:8282/solr/#) (NB - Solr runs on ports 8282 in our server.) I logged onto the remote server where Solr was installed and ran > bin/solr status I got this message - Found 1 Solr nodes: Solr process 4365 running on port 8282 ERROR: Failed to get system information from https://localhost:8282/solr due to: javax.net.ssl.SSLException: Certificate for doesn't match any of the subject alternative names: [*.ishippo.com, ishippo.com] We figured that it could be an SSL issue and tried accessing the Solr dashboard through plain HTTP by plugging in our server's IP address. This time, we could access the Solr dashboard. But our website works solely by https, so the Solr query gets blocked every time. It seems that only https connections are being blocked by Solr and its port (8282). Everything works fine on the other ports, and on http. We contacted our SSL certificate authority, and they said everything was fine from their end. They even made us perform openssl tests and send them the output. but they couldn't find anything cause from their end. (I have the openssl messages returned from the tests, which are long. I can share them if someone needs it) What could be the issue here? I have tried so many things in order to fix this to no avail. Does anybody know what's going on and help a user out? Thank you for your patience, iShippo Here is a summary of the problem - - Solr dashboard (located on https://api.ishippo.com:8282/solr/#) is not accessible. - Only port 8282 (which Solr runs on is affected). Services also running on api.ishippo.com on other ports are running fine. - Solr throws a javax.net.ssl.SSLException error. - We discover we are able to access the Solr dashboard by looking up the IP address of our server (and not the URL) on http (http://220.127.116.11:8282/solr/#) - Our platform runs soleley on HTTPS, so we're not able to go around it by using http. - Our SSL certificate authority couldn't find a cause on their end.
