Today i ran into a problem while trying to crawl/index from the User Profile :

The start address sps3://…. cannot be crawled

The object was not found

sps3 is the protocol to crawl User Profile informations on SharePoint.

Possible reasons :

• You are having a multi farm architecture and configured AAM : solution is to change the URL after sps3 to use the Url you configured on your DNS and AAM
• You are using HTTPS : change sps3:// with sps3s://

If it helped you, please leave a comment.
