I have a lab for some network studies and use my pi-hole for all my DNS at home. There is a specific DNS entry “portal.silverpeak.cloud” that will not resolve from devices pointed to my Pi-Hole.

I can see the hit in the log and it resolves. When I bypass my Pi-Hole and point to other servers e.g. 1.1.1.1, 8.8.8.8, or 9.9.9.9 , the devices resolve the name just fine.

Any suggestions on what to look at?

Edit: Here is some log data on my Pi-Hole for the request:
