Visitors to the website coronatest.nl inform us that the site is not available at certain times. Of course it can always be due to crowds, but there can also be other problems and associated solutions. In this article we will discuss what you can do to still be able to reach the site.
When you go to the coronatest website, access may be denied or the site may not load. In many cases, visitors encounter the 403 error. That’s a typical http status code that indicates you can’t access certain site components. The bottom line is this: the server of the website in question understands the request (as in: you want to enter the website), but cannot fulfill that request for a technical reason.
That technical reason almost always has something to do with things going on behind the scenes. This is possible because a specific page is missing (index.html or .php), incorrect permissions on files or folders or an incompatible plugin. As a website builder or administrator, it is the intention that you solve those problems, so that people can access your website again. As a visitor there is nothing you can do about this. But what can you do yourself?
Visit Coronatest website
Sometimes you cannot reach coronatest.nl for another reason. The problem then lies not so much with the provider, but with the user. As a user, various things can play into this that can cause problems. For example, we have discovered here in the editorial that you do not always come to the website when you use a VPN. That probably has something to do with foreign servers, because such a VPN redirects the traffic. If you use a VPN yourself, it would be a good idea to temporarily disable that service when you want to make an appointment on the site.
In addition, ad blockers or tracking blockers can throw a spanner in the works. Those blockers can be set up in such a way that they can block images, advertisements and web forms, if such a site – for whatever reason – is suspected of malicious behavior. Do you use such a blocker, which may or may not be installed directly in your browser? Then temporarily disable it, so that you are sure that the problem is not there. Speaking of browser extensions, disable them all just to be safe. You may have one that unintentionally causes problems.
General Solutions
If the above solutions don’t help, there are some general solutions you can try. The simplest solution: try a different browser. Go for an unused browser. On Windows you often already have Edge installed, while macOS users can of course always lean on Safari. If you already use those browsers, download another, such as Chrome, Firefox or Brave. There is no shortage of good browsers these days, fortunately.
If you can’t or don’t want to use another browser, we still have some options left. It is therefore a good idea – regularly, but certainly in this case – to delete the browser data. Within the settings of the browser you are using you will find the option to clean up and clean up your browser somewhere. With the Google Chrome browser, for example, this option is called Clear browser data. You can set a period (indicate that you want to delete everything) and check what you want to delete. Also find as many options as possible here, so that you are sure that you delete everything.
This concerns your browser history, cookies and other site data and images that a browser has cached. But you can also delete your download history. If you use a built-in password manager: leave that information. The fault cannot lie there. Sometimes cookies or other data make it difficult when you visit a website like coronatest.nl. That’s why it’s a good idea to delete it when you run into problems.
DNS can also cause problems
Finally, we can look at the DNS. That abbreviation stands for Domain Name System: this is the system and network protocol used on the Internet to translate computer names into numerical addresses and vice versa.
What we can do is flush the DNS, as it is called. On Windows, open the Command Prompt by opening Start and typing cmd. Open the program with your right mouse button and select the option Open as administrator. After opening, type the following line: ipconfig /flushdns. Once the text ‘flushed the DNS resolver cache’ appears, the task is complete. Exit the program and restart the computer.
You can also try to adjust the DNS server on your Windows computer. You proceed as follows.
1. Open Start and open the settings.
2. Now go to Network and Internet and then to Adapter options changes.
3. Right click on the connection you are using.
4. Click Properties.
5. Select the Internet Protocol Version 4 (TCP/IPV4).
6. Click Properties.
7. Click on ‘Using the following DNS server addresses‘.
8. Enter an alternate DNS here. A good alternative is Open DNS with the addresses 208.67.222.222 (primary) and 208.67.220.220 (secondary).
9. Click OK.
Now you have adjusted your DNS and you can close the windows and try again. If it still doesn’t work after that, then there is probably something else going on that has nothing to do with your browser(s). It can also be a technical problem of the website or, as mentioned earlier, the traffic on the site in question.
