Error creating ssl certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

I found similar questions here about this problem but none of them work

Hello @ahtisham,

Are you sure? Because seems you are using Apache on CentOS.

$ curl -IkL
HTTP/1.1 200 OK
Date: Sun, 17 Oct 2021 07:58:50 GMT
Server: Apache/2.2.15 (CentOS)
X-Powered-By: PHP/5.3.3
Connection: close
Content-Type: text/html; charset=UTF-8



No i am sure that configuration is of my old instance that i deleted but i have never used PHP something is wrong with curl :sweat_smile:

curl is working fine :wink: The problem is that your domain is reaching the parking page at so it is not pointing to your server and you should fix that before trying to issue a certificate.

Also, doesn't seem your domain registrar is namecheap...

But i can access the site fine with http it doesn't point to

I linked my nameserver of aws with namecheap couple of hours ago myself.

everything seems to working fine except the ssl

Believe me, it doesn't work at all.

I tried to reach your site from Spain, England, Germany and France and I always reach the's parking page.

The whois for your domain doesn't show namecheap as your registrar:

$ whois

The DNS are pointing to turkticaret:

$ dig ns +short

And the current ip used by your domain ( is a turkticare ip.

$ whois

I don't know how you are reaching your site, maybe you have override the ip in your hosts configuration or you are accessing via proxy or vpn... the thing is the rest of the world can't reach your site so something in your dns and or registrar changes is not working fine... maybe it needs more time to propagate changes... but for com domains these changes are performed in a few minutes.



I don't know what i was thinking when i was creating the certificate it was rather than :man_facepalming:

I'm glad you finally issued the certificate for your domain
