Warning: stream_socket_client(): unable to connect to tcp

I’m not quite sure what to make of this. Were there any other error messages given?

But, as always, I would temporarily disable ALL plugins and switch back to the default Twenty Sixteen theme and retest to make sure the issue isn’t a 3rd party incompatibility issue.

Plus, between the time when your site didn’t have this issue and now, have you made any changes to your site?

Oh, and have you tried to reproduce the issue on multiple browsers and computers? Moreover, have you completely wiped your browsers’ cache and retested?

I tried also change Theme and this is the same.
Always at first load of this – mobileuiux.pl wordpress page I have warning

Warning: stream_socket_client(): unable to connect to tcp://mobileuiux.pl:80 (Connection refused) in /var/www/html/wordpress/wp-includes/class-wp-http-streams.php on line 150

Next time when you refresh page is fine.
When you close session or browser tab I’m getting again same warning.

please help… how could i solve this warning..really confused why this occur…please help
