Websites from blocklist aren't being blocked

Help
1

Please follow the below template, it will help us to help you!

Expected Behaviour:

I have a couple of websites that I want to have blocked from certain devices. I had the clients in groups, and then the groups assigned to domains. At one point the blocking was working, but when I went to add a new site today I noticed none of the blocking was working. The client I am testing from does only show 1 dns server, and I have flushed the dns cache (more than once), as well as restarted Pihole.

I am sure this is something small and stupid that I missed, but I would appreciate any assistance you can give me.

Actual Behaviour:

Sites are not being blocked as they previously were on target machine.

Which set of domain blocks are you referring to, and on which of your devices?

Also, for your iPhone, you have not entered the IP of the device, but have entered a local domain name for the device.

I just checked the youtube blocks, and they are working. The other two are not though (urbandictionary and nexterglobal), when accessed via the laptop. I also tried to access urbandictionary via the iphone and it did not block it there.

So domain 3 and 6 aren't working on either device. Domains 4 and 5 are working on the iPhone.

The regex (\.|^)urbandictionary\.com/$ does not pass a syntax check at https://regex101.com.

If you enter urbandictionary.com in Pi-hole as a wildcard domain, Pi-hole produces this regex which is valid:

(\.|^)urbandictionary\.com$

From the terminal or command prompt on the laptop, what are the outputs of the following commands:

nslookup pi.hole

nslookup heroes-wb.nextersglobal.com

nslookup flurry.com 192.168.13.2

okay that fixed the Urbandictionary. I had just copy/pasted the url in there and forgot to remove the trailing / before saving. As for the other question the results are below. I think I may have answered my own question though. the heroes-wb and hero-wars.com are essentially the same site (I think the nextersglobal one is where the actual game file is served from). Pi-hole can't block IP's though correct, so I would need to add a second entry to block hero-wars.com?

C:\>nslookup pi.hole
Server:  pihole
