SSL23 ERROR Unknow

Hello,
I also have the same configuration and the same mistake with Lets Encrypt:
error: SSL routines :: 140770FC of SSL23_GET_SERVER_HELLO: unknown protocol

Hi,

About this error with Lets Encrypt at OVH :

error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

I did some tests with my own extern script (WP-Cron url) :

http://xxx.com:443/blog/wp-cron.php

instead of :

https://xxx.com/blog/wp-cron.php

and the error disappears.

Do you have the possibility to implement this type of URL when it’s that error?

Hi,

OVH fixes the issue (January 2017):

Since the HTTPS deployment, it cannot be possible to call a link from their site with https using curl (PHP), or calling their website in HTTPS from a cron. The standard error message received is “cURL error 35: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol”

A workaround was to call http://myweb.site:443 instead of https://myweb.site.

We will deploy a solution to do https call working. But, in this case, the workaround will not work anymore. We planned to deploy it in January…

Also you can add this in your theme fonction to force CRON SSL/HTTPS:

function force_cron_ssl($url) {
	if ( $url == "https://yoursite.com/blog/wp-cron.php" ) {
		$url = "http://yoursite.com:443/blog/wp-cron.php";
	}
	return $url;
}
add_filter( 'site_url', 'force_cron_ssl' );
