When you open the browser, you plan that everything will be in normal mode. But what if the computer does not want to work as it should? And reports that the server certificate is invalid? In this case, you need to check how everything works, whether everything is set correctly, and if there are any problems. You can see this message on large sites (invalid Google server certificate, VKontakte), which simply cannot allow such a mistake.
What does it mean?
For starters: why is this notation used? What does it mean when the computer reports that the certificate submitted by the server is invalid? Thus, the computer says that the electronic documents of the site that he provided have some kind of inaccuracy, so the machine has reason to doubt its authenticity or functioning. This problem can occur both due to server problems and inaccuracies in the user's EOM. If we consider the first version, then there may be this:
- There is a problem with the certificate authority site. All these confirmations are issued by special organizations. And like any other, they are not immune from possible problems like terrorists, earthquakes, landslides, damage to transmission lines and many other problems. But this happens extremely rarely, and you don’t really have to rely on this item.
- Problems with the site due to technical problems or intentional harm. Here, too, something may go wrong. The system administrator clicked something wrong or attackers are conducting a server attack, the result is one - the server certificate is invalid. But this also rarely happens.
The main problems of this type occur mainly on the client computers of users. There may already be a wider range of reasons, therefore the main ones will be named:
- Incorrectly set time.
- A problem with software designed to view the World Wide Web.
And how to fix these problems? This issue will now be given attention.
Time setting
The most popular reason. If the computer has the wrong time or date, then when all the files are received, the machine sees that the parameters do not match and informs the user that the server certificate is invalid. This is all done in order to protect a person who goes online and prevent the loss of important data for him. It is very easy to fix this problem - for this it is enough to just fix the time for the current date and time, and this problem will not be. This case accounts for approximately 95% of such incidents.
Remove certificate verification
What if the problem is not in time, but in something else? And whatever you do, the server certificate is invalid and remains in that status? And while access to data should be obtained urgently? Well, if there is no time to look for the true reason, then you can do it simply and efficiently - just turn off certificate verification. To do this, go to your browser settings, then go to the security section and take the necessary actions (a more specific plan depends on the program used). And the computer will not be able to block access to the site, because the server certificate is invalid. But perform these actions on only those network resources that you trust.
Conclusion
Why were so few reasons and solutions addressed? The fact is that with their help you can solve the bulk of the problems that arise when the server certificate is invalid. If they didn’t help, then it’s unlikely that you can already fix the malfunction, and then you need the help of a specialist.
