In our implementation, we are unable to enable the "View on Site" functionality in SDL Web 8.5.
The option, whenever clicked for any page re-directs to a localhost path - http://localhost:8080/group/newsletter/index.html etc., which I am not sure where I could update to set it to our web page path - http://abcdef.esssa.com/group/newsletter etc..
Is there any config file which needs to be updated with the URL?
To work with View on Site functionality you need to configure your website URLs to Create the Website and Web Application into Topology Manager.
Add-TtmWebsite -Id Staging_Website -CdEnvironmentId StagingCdEnvironment -Baseurls @("http://abcdef.esssa.com", "http://localhost:8080")
please change your customer environment websiteId and CdEnvironmentId
Note:
View on site functionality always refers to the first base URL from the above configuration if you have multiple base URLs configured.
I hope it helps
