I’m making a website on Prestashop and I’m hosting it on my own server (Apache 2 - Debian 8). I installed a SSL certificate with Certbot and everything was working fine. I had to enable SSL and force redirection of all http to https in Prestashop and everything was working after (all website pages were https).
Problem is it only works for few hours (about 3 hours). After that I’m unable to reach the website (FrontEnd and BackEnd). To solve it, I have to restart the router of my server to make it work again for few hours.
I’m stuck with this problem and I dont know where to start or look.
If you have any idea what it could be or where to look I would really appreciate some help!
Thank you and sorry for my English it’s not my first language.
