Strange issue with SSL on PHP calls

[Max Amigo]

Hi guys!

I have Froxlor server with Apache, Let's Encrypt and  PHP-FPM. I have a single WordPress site installed. My website is behind cloudflare.  I have a problem with WP-Cron service on Wordpress.

In the error log I see:

There was a problem spawning a call to the WP-Cron system on your site. This means WP-Cron events on your site may not work. The problem was:

stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert
handshake failure stream_socket_client(): Failed to enable crypto stream_socket_client(): unable to connect to 
ssl://your-silly-somain-123.com:443 (Unknown error)

 I could not find easily anything related to this issue in the google, so I am searching... I only saw something about Apache misconfiguration.

 

Any ideas are welcome!

With a better wording I found a better explanation: https://www.journeybytes.com/wordpress-cron-error-503-by-cloudflare/

depends, are you using the cloudflare proxy or just DNS? cloudflare can also provide ssl certificates which can be very irritating (issued by sni.cloudflaressl.com).

So, does you domain in froxlor have SSL enabled and a valid certificate assigned? Can you open your-silly-somain-123.com:443 from the error message in your browser without errors?

I don't know much about SSL stuff but everything was working perfectly. At first I had DNS set to my server, and I used Let's Encrypt on my domain - everything was fine.

Then I switched to cloudflare for security issues, so nobody cad DDOS me. Again - everything seemed to be cool until I realised that after switching to cloudflare WP-Cron stoped to work.

I believe it is because it is kind of WEB Cron?

Another option it manually call cron.php script from system cron.

Trying to understand what is better for me.

The best way to integrate the wp-cron is locally on the server

1) disable cron to be executed when visiting the site in wp-config.php, just add:

define('DISABLE_WP_CRON', 'true');

2) call wp-cron e.g. every 5 minutes via cronjob

For me works:

*/5 * * * * /usr/bin/wget -q "https://best-online-casino-australia.com/wp-cron.php?doing_wp_cron" -O /dev/null

 

Thank you!!! 🍺
