These tools are helpful: How do I determine what domain an ad is coming from?
Note that Pi-Hole is a domain blocker, not a content blocker. In both of these URLS, the protocol is https, the domain is www.dealnews.com, and the path is what follows. Pi-Hole blocks at the domain level, so if you have www.dealnews.com blocked, then neither of these URL's should load, since they are both on the same domain.
The fact that this is not being blocked in all cases indicates that you may have a DNS bypass, where your clients are sending some of their DNS traffic to a DNS server other than Pi-Hole.
How do you have your router and clients set up to use Pi-Hole? Is Pi-Hole the ONLY DNS listed in either the router or the clients?
