Unable to access any Visual Force Pages or download static resources.

Hi, I'm unable to download any static resources and access visual force pages in my org getting the following error 
In Classic View -  'Your connection is not private
Attackers might be trying to steal your information from org domain_name(for example, passwords, messages, or credit cards). Learn more
NET::ERR_CERT_COMMON_NAME_INVALID'.

In Lightning View - 'The webpage at https://domain_name.visualforce.com/apex/Traveller?ltn_app_id=06m24000000TwKeAAK&sfdcIFrameHost=web&isdtp=p1&clc=0&RId=a1q1o000004fEAE&sfdcIFrameOrigin=https%3A%2F%2Fdomain_name.lightning.force.com&nonce=46b0d708cceb3eb096f8589c743667ef2e7bf0f2177f683a70eeae6c99725c0a&tour=&ra=pdf might be temporarily down or it may have moved permanently to a new web address'. 

Please can anyone assist us with this issue.

HI Syed,

When Force.com Site users use a HTTPS URL with the force.com extension, they might run into an insecure connection error.   Attempting to use HTTPS on the force.com subdomain results in a certificate error. 

The right URL usage would be:

HTTPS: https://xyz.secure.force.com

HTTP: http://xyz.force.com


It is key to note that the Require Secure Connections (HTTPS) option can help ensure that anyone who accesses http://xyz.force.com gets redirected to https://xyz.secure.force.com

Apologies for the delay. Can you check if there have been any firewall changes at your network end?
