Exception while blocking domain using Advanced Blocking

Technitium 11.5.3 with Advanced blocking 6.1

I am trying to configure the advanced blocking for a domain for a specific host but the dns server raised an exception:

[2023-12-05 14:46:08 UTC] [192.168.1.120:62838] [marco] DNS application 'Advanced Blocking' app config was saved successfully.
[2023-12-05 14:46:23 UTC] [192.168.1.81:35382] [UDP] System.NullReferenceException: Object reference not set to an instance of an object.
   at AdvancedBlocking.App.ProcessRequestAsync(DnsDatagram request, IPEndPoint remoteEP) in Z:\Technitium\Projects\DnsServer\Apps\AdvancedBlockingApp\App.cs:line 582
   at DnsServerCore.Dns.DnsServer.ProcessBlockedQueryAsync(DnsDatagram request, IPEndPoint remoteEP, DnsTransportProtocol protocol) in Z:\Technitium\Projects\DnsServer\DnsServerCore\Dns\DnsServer.cs:line 2669

this is the part of the config file with the group config:

 {
      "name": "kids",
      "enableBlocking": true,
      "allowTxtBlockingReport": true,
      "blockAsNxDomain": true,
      "blockingAddresses": [
        "0.0.0.0",
        "::"
      ],
      "allowed": [],
      "blocked": [
      "example.com"
      ],
      "allowListUrls": [],
      "blockListUrls": [
        "https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/social/hosts"
      ],
      "allowedRegex": [],
      "blockedRegex": [],
      "regexAllowListUrls": [],
      "regexBlockListUrls": [],
      "adblockListUrls": []
    }

The blocking for the domains in the blockListUrls section works, so the networkGroupMap should be configured correctly

Thanks for reporting this. However, I would need to have the exact config to be able to reproduce this bug. Do share the config you have over here or send it to support@technitium.com if you do not wish to disclose it publicly.

I did some tests and found the exact issue. Will release a fix soon.

Advanced Blocking App v6.1.1 is now available that should fix this issue. Do update the app and let me know your feedback.
