I have repeatedly run through the certbot setup on my ubuntu 16.04/apache2 box but despite the script claiming it was setup successfully when I visit my site I no longer get the default site. I just get:
mysite.example sent an invalid response.
ERR_SSL_PROTOCOL_ERROR
Is there any examples of vhost files I can use to figure out what is going on?
I have many subdomains to also setup but first I need to get the default site working again.
