One of my sites suddenly went offline with this error, first, it was saying the site was no secure, I got an email the SSL was going to expire, so I renewed it. Less than 24 hours later is offline with this error and I cannot get it back online. I edited the vhosts and removed the SSL all together and I’m still getting this.
I am out of ideas, I have no idea why this site (out of 6 on the server) is down and I cant get it back up.
