ERR_SSL_PROTOCOL_ERROR

Suddenly on all my websites, without touching anything or doing anything.
I'm talking about 18 websites
ERR_SSL_PROTOCOL_ERROR
Any idea what might have happened?

After several attempts at restarting, etc., everything worked again on its own, or so I think.
I just rebooted Ngnix and everything was operational again, which is strange.

I had a similar problem with my live client site, yesterday.
Let's encrypt hadn't auto updated the SSL certificate. When manually renewed, a SSL RECORD TOO LONG happened.
I needed to rebuild the vhost, to get the site back working again.
Very strange. 

This is crazy every day there is a different problem, you can not rest, every day you have to be checking that everything is working properly.
Now I have a spam problem with one of my clients and the page he sends you is in Russian and google does not translate it for me.
Anyway every day a different headache
