I’ve setup a new Wordpress droplet, and I believe I’ve got Certbot working fine too.

However, I find that after a while (15+ minutes), if I go to the site in my browser I get a “This site can’t be reached / DNSPROBEFINISHED_NXDOMAIN” error in Chrome, but then it comes online after a few seconds.

I’ve checked /var/log/apache2/error.log and found the following…

[Thu Nov 25 13:42:11.305444 2021] [mpm_prefork:notice] [pid 846] AH00169: caught SIGTERM, shutting down
[Thu Nov 25 13:43:48.303502 2021] [mpm_prefork:notice] [pid 865] AH00163: Apache/2.4.41 (Ubuntu) OpenSSL/1.1.1f configured -- resuming normal operations

I’ve also used the following command to see if anything is killing Apache, but I’m getting no results…

grep -i kill /var/log/syslog | grep apache

Any help much appreciated!

Hi @notpatrick,

I think the issue was with your DNS. If you just changed your DNS it can take up to 48 hours for it fully propagate.

Are you experiencing the issue now? Wait for your DNS to stop propagating and see if this is still being experienced.

  • Thanks so much - it does seem that it took 24-48 to sort itself out and is now working fine without anything else done at my end.

    Much appreciated!

    • Hi @notpatrick,

      I’m glad to be of help. Yes, usually the errors you’ve experienced is when your domain is not pinging or not pinging to where it is suppose to, in 99% of the cases it’s DNS related.
