Internet not working with Kuwait ISP (STC) when using NextDNS

Hi 

STC ISP from Kuwait purportedly blocks the internet when using NextDNS. 2 other ISPs function normally with NextDNS.


STC Kuwait - No internet when using NextDNS (even AdGuardDNS)

Zain Kuwait - No problem

Ooredeoo Kuwait - No problem 

 

Testing methods:

-Multiple devices with DNS configuration OK status 

-3 different ISPs tested

-Wifi and Mobile Data

-Even tried all NextDNS settings or rules disabled on web panel BUT with DNS properly configured and enabled.

-NextDNS App and configuration profile tested separately 

-Ultra low latency network enabled/disabled 

-Network Bypass methods enabled/disabled

ALL of the above testing leads to the same result.

 

I contacted my ISP technical team and they state NextDNS blocks/does not recognise their network (strange!).

 

Observations on ISP that blocks NextDNS <some services work/don’t work>

Safari/Chrome - Web browsing don’t work

Instagram - Works!

WhatsApp - Text messages and voice call work. Media does not load (voice messages, photo, video)

Email clients - Mail app, Outlook don’t work.

Ring - Notifications work. App does not load.

App Store, Phone settings, updates don’t work.


Support help:

-Anyone else from Kuwait using NextDNS on STC experiencing similar issues?

-Could someone from NextDNS extend some support if this is indeed NextDNS issue or service being blocked by STC ISP?

 

Disclaimer:

I am reporting this on this forum as per STC ISP support team instruction to contact NextDNS to solve this issue. (Customer to contact NextDNS and then provide support info to ISP via email).

      NextDNS Thank you for your response.

      5G Internet connection used from an iPhone with NextDNS profile.

      iPhone - No connectivity as explained in my initial post.

      Mac - Used to run test. Mobile Hotspot used from iPhone with NextDNS configured and turned on.

      NextDNS profile ENABLED on Mac: Internet NOT working. Can't run test.

      NextDNS profile DISABLED on Mac: Internet working. Test result: https://nextdns.io/diag/bd41c330-0545-11ee-9bc2-89aa0593afb0

      NextDNS Can this tool be used on iPhone directly?

    For comparison. This is the result from another ISP (no nextdns config on Wifi router) with DNS configured on Mac directly. test.nextdns.io on Safari gives: 

    "status": "ok",

    Zain ISP: Internet works with NextDNS configuration.

    Test result: https://nextdns.io/diag/f24877c0-0542-11ee-9bc2-89aa0593afb0
