SharePoint 2019 Search is broken after configuring SSL

Question

We have implemented SSL and redirecting http to https based on below scenario.

1. Default Zone URL: http://servername:10101, we extended this to intranet zone with https://servername.projects.com:10105 and updated the bindings in IIS. Sites are working fine with SSL URL.
2. in IIS for http://servername:10101 we have created URL redirect to https://servername.projects.com:10105 so that users will be redirected to SSL URL for old links. Redirects are working perfect.

When we are trying to search anything in https://servername.projects.com:10105 is not showing any result and no error in ULS. We have tried enabling NO SSL Warning in search service application and also tried with SSL Urls in contents source but no luck. We have restarted all search related services but no luck. We can see crawled contents from SSL URL in Crawl Log- URL.

Answer 1

You need to change the AAM on the Default Zone as that is what SharePoint needs to crawl; or keep the AAM you have for the DZ and direct users to the new URL without the IIS redirect in place.

Answer 2

How did you set the content source? You need to make sure you are using the default zone url.
