Just updated pi-hole yesterday. Added the pi-hole IP to my Ubiquiti USG and ad blocking was up and running. But last night I finally got around to watching TWD but streaming would not work (gets stuck on "loading...". I noticed that just about everything loads slowly (websites, etc..) but I let this run over 5 mins and nothing. Once I point the USG off pi-hole and reboot the Roku it works just fine. I tried whitelisting AMC.com but that didn't seem to help.
Expected Behaviour:
AMC Movies start streaming
Actual Behaviour:
Can see video library can select show and episode but streaming will not start
