Egr cooler leaking externally?

[Burlyman]

I have an oil leak that appears to be coming from the front end of my oil filter base housing.( 2015 ISX 15) I have posted a youtube video. Has anyone encountered anything like this. Video at around 47 seconds in shows the best view of the leak. I've never had one of these off so curious to know if that round end has a seal. It's hidden behind the alternator bracket. Truck only has about 60K miles. Out of the scope of warranty of course.
