For those of you working with websites on a regular basis, errors specific to the CMS such as the white screen of death or database connection errors are somewhat common occurrences. But another subset of errors you will probably stumble upon are those tied to your internet connection and DNS.
When a user enters a URL in their web browser, DNS gets to work to connect that URL to the IP address of the actual server. This is called DNS name resolution and involves a DNS recursor querying various nameservers to figure out the actual IP address of a server. If DNS fails to resolve the domain name or address then you might receive the DNS_PROBE_FINISHED_NXDOMAIN error. The NXDOMAIN part stand stands for Non-Existent Domain. Read more about DNS and how it works.

Sometimes VPNs and Antivirus software can conflict or override your network settings, including your DNS servers, etc. If you have any running, try temporarily disabling them (closing them) to see if it resolves the DNS probe finished nxdomain error in Chrome.
ThousandEyes tests confirm there was a second, separate issue with Facebook apps & services today that is now resolved. Unlike the Oct. 4 outage (see analysis below), Facebook and Instagram were reachable, but tests showed increased server errors and that the applications were running very slow for some users, in some cases failing to load.
Recently, I faced this issue where Facebook was not loading in the Chrome browser. Google Chrome is already getting slower by the day and added errors and issues like these only make the problem worse. Not being able to access my Facebook account gave me a headache and I found a couple of ways to troubleshoot it.
In a digital world hooked on instant gratification, one of the last things you want to experience when browsing is an error message, such as ERR_CONNECTION_REFUSED. This can be incredibly frustrating, and may even be a sign that something serious has gone wrong.
For average users, the really confusing errors are the ones where it can sometimes hard to distinguish between a problem with your WordPress site and something else, such as a networking or browser issue.
Unfortunately, encountering errors comes hand-in-hand with using the internet. There are hundreds of possibilities, from the white screen of death to the classic 404 error , the ERR_CONNECTION_TIMED_OUT error or the ERR_CACHE_MISS. Trust us, our support team deals with all sorts of WordPress errors on a daily basis. So this is nothing new for us.
A simple way to check whether this is the case is to visit another web page. If the error message occurs again, the problem most likely originates with your connection. If the second page loads correctly, however, the first site was probably at fault.
If a stored entry no longer matches the current version of the website it refers to, technical errors like the ERR_CONNECTION_REFUSED message are not unusual. Fortunately, clearing your DNS cache is a quick and easy solution.
I have tried all the options listed above many times but I still get the same error. The site works on windows laptops and on other macbooks, phones and ipads. But just on doesnt open on my macbook pro . It has been a few months and I have not still not been able to figure it out. Any help will be appreciated. I have also spoken to the hosting company of my site multiple times to no success. I do think the problem is on my side.The site I am trying to access is my portfolio site made in wordpress.
One of the reasons the \u201cThis site can\u2019t be reached\u201d error is so frustrating is that Chrome can be unclear about what causes it. Moreover, the message can appear alongside a broad range of error codes.\nFor example, you can get that notification if you run into the\u00a0DNS_PROBE_FINISHED_NXDOMAIN error:\nThat same error message will also appear if your connection times out or if you encounter the\u00a0ERR_CONNECTION_RESET code:\n\nClearly, Chrome uses the \u201cThis site can\u2019t be reached\u201d message as a catch-all description for a lot of errors. By and large, the most common causes are:\n\n\nDomain Name System (DNS)\u00a0resolution errors\nConnections that time out\nAn overall failure of your internet connection\nMisconfigured internet, network, or firewall settings\n\n\n\n"},"name":"What Causes the \u201cThis Site Can\u2019t Be Reached\u201d Error?","@type":"Question"}]},"@context":"http:\/\/schema.org","@id":"http:\/\/data.wordlift.io\/wl0150038\/entity\/salman_ravoof","@type":"Person","description":"Salman Ravoof is the Technical Editor at Kinsta.

In one of the stranger side effects of the Facebook BGP Routing error outage, the Facebook domain itself was listed in a whois lookup as being available for registration, presumably because the Facebook domain essentially no longer exists.
The "Temporary failure in name resolution" error occurs when the system cannot translate a website name into an IP address. While the error sometimes appears due to a lost internet connection, there are multiple reasons why it may show up on your system.
If your resolv.conf file contains valid DNS servers, but the error persists, it may be due to misconfigured file permissions. Change ownership of the file to the root user with the following command:
Your business has gotten along fine without knowing much about what DNS is or what it does. You probably didn't care too much about it. That was true until October 2021, when Facebook experienced a DNS error which brought on the longest stretch of downtime it ever had since 2008. Suddenly, many business owners like yourself started asking, "What is DNS?"
Of course, since DNS is a major part of the internet, it's also a potential target for threat actors. Attacks like DNS hijacking, where hackers take over logins belonging to DNS providers and registrants then redirect any incoming traffic, are commonplace. Attacks like those are both easy to execute and low-cost because they rely on victims not taking basic security measures. Adding that extra layer of security can help ensure you protect your online presence.
In this article, you can see the best methods to quickly get rid of this error and improve your browsing experience. We know how frustrating it can be to not be able to surf the internet the way you want to. This is why our methods are easy and quick to execute, making troubleshooting a short process.
Some popular websites such as www.facebook.com send back DNS responses with very low Time To Live (TTL) values. The screenshot below is from a packet capture. It shows that the DNS server responded back to the request and indicated that the TTL of the entry was only 20 seconds.
This means that a computer would continue to use the IP 69.171.224.14 for www.facebook.com for 20 seconds, and after 20 seconds it would re-resolve the DNS entry and use the new IP address the DNS server responded with :
The side effect of this is that the inside client will start using a new IP address for www.facebook.com one minute before the ASA updates its own IP to hostname mapping, and during that time the access-list line might not match. This would result in the clients being permitted or denied intermittently when they access www.facebook.com.
Another reason to stay away from URL filtering using FQDn's... if you were to create an object and use it to block the following fqdn "www.facebook.com" users may still be able to get to "facebook.com". This is because both FQDN's resolve to different IPs. Blocking one FQDN for a website does not always block all the possible was of accessing it:
This is very good document and useful for simple acl-dns blocking site such as twitter, facebook, pandora...in the work place, but I will also learn to use external URL filtering server or application inspection on the ASA as recommended
My guess is that your ISP is doing something that affects DNS resolution of one of the domains involved in the FB page request, perhaps directing it to an Akamai server that is not properly configured to serve a Facebook page, thus causing the error.
Similar to the "ScriptError: Authorization is required to perform that action" error message, this error from Google occurs when logged in into multiple Google accounts at the same time. Instead of seeing the regular add-on interface, you'll instead see an image like this:
This error indicates that the request is unable to complete successfully, but neither the API nor Google returned any specific information about the cause of the problem. The primary known cause of this error is a request that takes too long to complete and therefore hits Google's 6 min/request processing limits as described here. 2ff7e9595c
