How are you hosting your site?
Please install the plugin https://wordpress.org/plugins/health-check. You’ll probably have to do so manually. Once it’s installed and active, report back with the contents of the debug tab.
Before reading your post I was browsing through different posts and was trying to resolve the above mentioned error message and I have ended up in a blank page error that says[I had disabled the firewall service]
“This site can’t be reached 10.20.0.16 refused to connect.
Search Google for admin plugins
ERR_CONNECTION_REFUSED”
I’m also unable to restart my httpd service, and when I check the status for httpd I get this message
[root@webserver ~]# service httpd status
Redirecting to /bin/systemctl status httpd.service
● httpd.service – The Apache HTTP Server

Do you have any idea what might have gone wrong?
try typing
httpd -S and also try looking at the system logs for the httpd unit

This is beyond the scope of WordPress support. I suggest you check the support mailing lists (or other support resources) for your operating system.
I guess SSL was the issue,I tried to switch SSL engine off in the /etc/httpd/conf.d/ssl.conf and I was able to go back to website without “ERR_CONNECTION_REFUSED” error.
But the above mentioned error i.e., “Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums. (WordPress could not establish a secure connection to WordPress.org. Please contact your server administrator.) in /var/www/html/webster/wp-includes/update.php on line 348” still exists!!
I will now try to manually download the Health Plugin and check.
