I got this error on one of my restaurant nutrition menu website - , it just happen randomly. I am encountering this issue sometimes, but sometimes not. Already told this problem to my web hosting but it seems they can’t fix it. Please help.
Have a look at this guide and it also covers debugging.
Already checked it and I can only do the first one which is checking if the SSL certificate is installed. It is valid. Don’t know how do I do the other stuffs.
