When using an HTTP proxy, the links produced by Artifactory, as well as certain redirects contain the wrong port and use the http instead of https.
Therefore, you must configure a custom base URL as follows:
On the Admin tab select Configuration | General
Custom Base URLfield.Set the Custom Base URL field to the value used to contact Artifactory
For example:
https://yourdomain.com
Please refer to General Configuration for more details about configuring the base URL.
