Why my sites not working properly?

someshzadesomeshzade Member
in Help

Hello,
I used to install Cpanel/whm on my contabo VPS. All the sites were working fine until today's morning. But suddenly now sites are not working! I check the DNS status of one site it's showing DNS Propagation Successful for just 2-3 locations.

DNS Result - https://www.whatsmydns.net/#A/kanakdigifex.in

Any Solution?

    kanakdigifex.in redirects to https://www.kanakdigifex.in and loads fine, so you probably installed CSF and got yourself blocked. Alternatively, same thing but with cphulkd, issues with your network, maybe you edited the host file on your computer and forgot, your ISP's resolvers haven't updated yet, could go on for days really. Hopefully you find something in there that fits :)

    What would you like me to check next?

    As for that, consider it irrelevant. If the nameservers are registered with the TLD (GLUE) and they're responding to DNS requests, then whatsmydns.net result has more to do with when you used the website than whether or not something is broken. DNS "propagation" is instant if your first lookup comes after the change is in place, but then it takes a lot longer for computers/servers that have more recently performed a lookup for the domain. This is why whatsmydns.net is a bad tool for people who do not deeply understand how DNS works, it can only show you the real time "propagation" of a few servers assuming you've performed lookups with it both before and after the change.

    Is it my server issue? or Domain issue?

    Querying a1.in.afilias-nst.in for NS records for kanakdigifex.in reveal both of these:

    ns1.kanakdigifex.net
    ns2.kanakdigifex.net

    Both of these resolve to 173.249.13.23. The IP 173.249.13.23, when queried directly, returns a record for kanakdigifex.in which in turn loads for me as I was able to show in the screenshot.

    How long ago did you configure all of this? Because from where I sit this looks to all be fine. Anything remaining should be about time.

    I'm able to access your site without any problems as well. Did you try clearing the DNS cache on your computer? I had a similar issue to what you described and i just needed to clear my DNS cache after changing the nameservers pointing to my website.

    Change your settings to use google dns servers 8.8.8.8 and 8.8.4.4

    Then go to https://developers.google.com/speed/public-dns/cache?hl=vi and clear dns cache

    Clear windows dns cache and chrome dns cache
    https://superuser.com/questions/203674/how-to-clear-flush-the-dns-cache-in-google-chrome

    And the regular chrome cache.

    Try to load your website.

    My ISP saves DNS cache without a way to flush it, thats why I started to use google dns.
