PiHole is not blocking anything else besides mask.icloud.com

[Martijn_van_Boven]

Expected Behaviour:
Pi-hole is blocking ads/domains that should be blocked.

Actual Behaviour:
The Pi-Hole is only blocking mask.icloud.com as in the screenshot below. If I add other domains to the black list from the query log it will be shown after as OK and is not blocked.

Debug Token:

Screenshots:

Raspberry Pi used: Raspberry Pi 2
pihole version: v5.18.3

I've added some adlists from my friend and have over 2.6 million blocked domains. althought the pihole still only block mask.icloud.com

Update, I've done some troubleshooting. Right now the pihole is blocking more stuff and think its blocking properly. But right now i get an error when i blacklist something:

While executing: attempt to write a readonly database. Added 0 out of 1 domains

Update, i've managed to solve the error. but now the pihole has the same problem again. It is only blocking icloud.com and nothing else

I have debugged a whole lot the past few days. It is working fine right now and i will close the forum if I can.
