How change port in the url?

I've added to email notification the artifacts:

<p>Build artifacts:</p>
<#list build.artifactsDirectory.listFiles() as file>
<a href="${webLinks.getDownloadArtefactUrl(build.buildTypeExternalId, build.buildId, file.name)}">${file.name}</a> (${file.length()}B)<br/>
</#list>

All worked well until we changed the port our website. How can I change port from 8085 to 8086? In the main config file I've changed port but in the email the artifacts have the old port 8085. When I click html report I redirect to "site:8085" but should to "site:8086"
