why is jira dashboard showing broken images?

I moved a jira instance to a new machine.  everything looks ok except many images are broken.  looking at the browser console, I see messages like:

Mixed Content: The page at 'https://berlin.elucidbio.com/jira/secure/Dashboard.jspa' was loaded over HTTPS, but requested an insecure image 'http://localhost:8080/secure/thumbnail/10830/_thumb_10830.png'. This content should also be served over HTTPS.

I am using apache in front of tomcat.  The apache config contains the following for the proxy part:

<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyRequests Off
ProxyPass /jira ajp://localhost:8009/jira
ProxyPassReverse /jira ajp://localhost:8009/jira

in tomcat, server.xml, I have:

<Connector port="8009" redirectPort="8443" enableLookups="false" protocol="AJP/1.3" URIEncoding="UTF-8"/>

<Engine name="Catalina" defaultHost="berlin.elucidbio.com">
<Host name="berlin.elucidbio.com" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Context path="/jira" docBase="${catalina.home}/atlassian-jira" reloadable="false" useHttpOnly="true">

<Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction"
factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/>
<Manager pathname=""/>
<JarScanner scanManifest="false"/>
</Context>

</Host>

Base URL is set to  https://berlin.elucidbio.com/jira

Digging a bit deeper into the html. I find two image url types that do not work.

https://berlin.elucidbio.com/jira/s/-o51zru/76002/1a0b7c420f02e282493b2b0883eb4b6d/_/jira-logo-scaled.png
 http://localhost:8080/secure/thumbnail/10828/_thumb_10828.png

what do I need to change to fix both of the URLs?

thanks in advance!

When you use a proxy in front of Jira, you should also be sure to include the proxyName, proxyPort, and scheme parameters in the Tomcat server.xml connector being used here.  Without these the Jira application does not understand that it's content is being served over a proxy.  So while your current connector looks like this:

<Connector port="8009" redirectPort="8443" enableLookups="false" protocol="AJP/1.3" URIEncoding="UTF-8"/>

 I think you should update this to make it look like this:

<Connector port="8009" redirectPort="8443" enableLookups="false" protocol="AJP/1.3" URIEncoding="UTF-8" proxyName="berlin.elucidbio.com" proxyPort="443" scheme="https"/>

After you make this change, you need to save that file, and then restart Jira for these change to take effect.   These steps are also mentioned in our guide Proxying Atlassian server applications with Apache HTTP Server (mod_proxy_http).

It would also be recommended to check that your base URL within the Jira system admin menu is setup to use https://berlin.elucidbio.com/jira/
