SOLVED Websites not loading on Opera mini

Not clear whether this is a cPanel issue but we have a server running cPanel and all websites hosted on it cannot load in mobile browser, esp. Opera Mini.

We have checked and ensured relevant IP addresses are not blocked but still we can't get sites on the server to load in mobile.

Any idea?

 

There's no error message. I have checked on 2 logs while trying to access the site:

# tail -f /usr/local/apache/logs/error_log | grep site
# tail -f /usr/local/apache/domlogs/site.com

and both don't show any entry when accessed via Opera Mini.

The error on the phone:
"
Could not locate remote server

You tried to access this address Example Domain. which is currently
unavailable . Please make sure the Web address (URL) is correctly spelt
and punctuated. then try reloading the page.

Make sure your internet connection is active and check whether other
applications that rely on the same connection are working.

"

I have also checked the iptables and can't see any entry for the IP address.

But I realized the error on the mobile browser shows 'https'. Could this be the problem?

Thanks.

 

I just realised the error message has 'https'. But I doubt there's a redirect since such redirect will show in the logs.

2ndly, all sites on the server cannot be accessed via Opera Mini, so I don't think it's .htacess.

3rd, cPanel itself and webmail cannot be accessed via Opera Mini.

4th, these issues are being experienced by all users (who number 100s) so problem can't be on user end.

5th, we also received this complain:
"
I'm trying to connect Jetpack to wordpress.com and it's popping an error.
"Error Details: The Jetpack server was unable to communicate with your site
example.com [HTTP 404]. Ask your web host if they allow connections
from WordPress.com."
So, do you allow connections from WordPress.com?
"

while this is not a mobile issue it seems related.

Generally, it appears there's a blockage but it doesn't show on firewall. We're unable to tell where else the blockage could be occurring.

 

Doesn't show anything.

On 2nd thought IP might not be a problem since on same phone other browsers work except Opera Mini.

Some Opera proxy IPs had been blocked. After unblocking them the Opera Mini now works.
