Android 10 device won't reach one specific web-site?



  • My android 10 device is failing to access one particular website. All others are fine. This started happening a few weeks ago.

    I have contacted my mobile ISP and they say their systems are working ok.

    I have contacted the website support, and they say I am not blocked by them.

    If I use a VPN, I can actually get to the website from the device.

    If I tether to the device from a PC and look at the tcp traffic, I can see that a UDP name server request for the website is repeatedly sent to the device, without reply.

    Can anyone suggest a remedy?



  • Yeah two solutions I am aware of

    1. Cause: improper configuration of IPV6 from ISP
      Solution: Go to APN settings and disable IP V6 (set apn protocol to ipv4 from ipv4/v6 and save the current APN)

    2. Cause: DNS issue
      Solution: Change DNS settings to Google's DNS or anything else (it's called 'private DNS' in some devices under settings)
