Site goes down randomely after migrating from http to https

[e.htabar]

Hi there,

I changed the protocol of my website to https yesterday. Everything went okay and the website got the green https lock.

The problem I face is that every now and then the server refuses to connect. When I restart the server, everything comes back to normal. Then after a while, users can't connect to the server.

What are the possible reasons and solutions to solve this issue?

Thanks,

Can you show us apache/nginx logs, when thin happening?
