I am managing a Droplet that hosts a light website named “https://onlyonecolombia.com/”. I’ve seen this page working perfectly fine a few days, but one of the customers says he can not see the page, no matter what browser he uses, no matter how many times he clears each browser’s cache, cookies, etc. from the beginning of time.
In the beginning I thought this was a local customer network issue, because while he was not able to see the page, I was, as well as many other clients in different networks and geographical areas. I rebooted the droplet once, and then the customer that said that could not see the page now was able to see it normally, but after a few minutes, he received the same error again.
But today I’m having the same issue. I can not access that page from Google Chrome, Firefox, Internet Explorer nor Opera. I don’t have any web-site blocking component (firewall, proxy, etc.) and I have not changed anything on the droplet (again, I’m the only one administrating it). Now if I reboot the droplet it does not seem to help.
Here are some tests I’ve made:

Also, here is the website’s Zone file content (as displayed by DigitalOcean in the DNS management page):
$ORIGIN onlyonecolombia.com. $TTL 1800 onlyonecolombia.com. IN SOA ns1.digitalocean.com. hostmaster.onlyonecolombia.com. 1435073711 10800 3600 604800 1800 onlyonecolombia.com. 1800 IN NS ns1.digitalocean.com. onlyonecolombia.com. 1800 IN NS ns2.digitalocean.com. onlyonecolombia.com. 1800 IN NS ns3.digitalocean.com. onlyonecolombia.com. 1800 IN A 22.214.171.124 www.onlyonecolombia.com. 1800 IN CNAME onlyonecolombia.com. *.onlyonecolombia.com. 1800 IN CNAME onlyonecolombia.com.
I have normal access via SSH, the Apache service is running, PHP is ok as well, I’ve extended the timeout settings in PHP to around 2 minutes, but the “ERR_CONNECTION_TIMED_OUT” error appears before that time in most of the cases. The databases are working fine as well.
Checking the server status via HTOP, I see the server is running fine, using less than 5% of the CPU, and around a 25% of the RAM (4 GB in total):
root@onlyonecolombia:/var/log/apache2# htop 1 [| 1.3%] Tasks: 102, 48 thr; 1 running 2 [ 0.0%] Load average: 0.06 0.03 0.05 Mem[||||||||||||| 906/3953MB] Uptime: 01:42:57 Swp[ 0/0MB]
Apache access and error logs do not show irregularities. The only thing I noticed there is that when I try to access the application from one of the browsers with the problem, the access log in apache does not move. I see that by using
root@onlyonecolombia:/var/log/apache2# tail -f -n 500 access.log
The same goes for the error log: no entries when accessing from a browser with the problem.
One thing to note, is that I installed iRedMail right after creating the droplet, because I needed this droplet to have a Mail server for that domain as well, which so far is working just fine.
We have SSL configured for this website, and internal redirection from HTTP to HTTPS in the main application, which is working fine too.
I’m running out of options here, and of course I can not tell all customers to use Tor browser to access this specific website, so I would like to ask for any advice here. If there is anything I’ve missed please let me know.
