 * 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 I
   am also at OVH. At home nothing works (not the CRON or manually) I installed 
   the extension you advise but it changes nothing. What to do please? Thank you
   for your help

 * I found the solution for me!
    This bypasses the problem with the certificate 
   Lets Encrypt. This should work for you: 1 – Change your wp-config.phh file by
   adding the following formula: **define ( ‘ALTERNATE_WP_CRON’, true);** 2 – Change
   your .htaccess file **RewriteEngine On RewriteRule \* – [E = noabort: 1]. RewriteRule\*–[
   E = noconntimeout: 1]. 3 – In the BACKWPUP plugin parameter then go to “Operations”
   and to “maximun time of execution” to 0. After several hours, this to work for
   me … 🙂

 * Same topic here : [SSL23 ERROR Unknow](https://wordpress.org/support/topic/ssl23-error-unknow/)
 * I suggest some rescue for developers (perhaps! 🙂 ).

 * Hi,
    Do you have a solution for simple BackWPup without cron ?
 * I tried to add
    ” RewriteEngine On RewriteRule * – [E = noabort: 1]. RewriteRule*–[
   E = noconntimeout: 1]. ” to my .htacess but I think there is a conflict with 
   others instructions. My .htacess is now:
 * ”
    RewriteEngine On RewriteCond %{SERVER_PORT} 80 RewriteRule ^(.*)$ [https://www.mywebsite.fr/$1](https://www.mywebsite.fr/$1)[
   R=301,L]
 * # BEGIN WordPress
    <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule
   ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME}!-
   d RewriteRule . /index.php [L] </IfModule> # END WordPress ”
 * Thank you
