When you open a browser, you plan thateverything will be as usual. 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 correctly set, and whether there are any problems. You can see this message on large sites (an invalid Google server certificate, "VKontakte"), which simply can not admit such a mistake.
What does it mean?
First: Why is this designation used?What does this 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, which he provided, have some kind of inaccuracy, thanks to which the machine has reason for doubts about its authenticity or the usefulness of its functioning. This problem can arise both because of server problems, and because of inaccuracies in the user's EOM. If we consider the first version, then there can be this:
- There was a problem with the CA website.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 very rarely, and there is no need to rely on this item.
- Problems with the site due to technicalmalfunctioning or deliberate harm. Something can also go wrong here. The system administrator did something wrong or the attackers are attacking the server, 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. Here the range of reasons can be much wider, therefore the main ones will be named:
- Wrong time set.
- The problem with the software intended for viewing the World Wide Web.
And how to fix these problems? Now this issue will be paid attention.
Time setting
The most popular reason.If the computer has the wrong time or date, when all 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 to protect a person who goes online, and to prevent the loss of important data for him. To fix this problem is very easy - for this it is enough just to fix the time for the current date and hour, and this problem will not be. In this case, about 95% of such incidents occur.
Remove Certificate Verification
What to do if the problem is not in time, but insomething else? And what would you do, the server certificate is invalid and in this status and remains? And at the same time access to the data should be obtained urgently? Well, if there is no time to search for the true reason, then you can act simply and effectively - just turn off the certificate check. To do this, go to the settings of your browser, then go to the security section and take the necessary actions (a more specific plan directly 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 only on those network resources that you trust.
Conclusion
Why were so few reasons considered andways of their elimination? The matter is that with their help it is possible to solve the bulk of problems that arise when the server certificate is invalid. If they did not help, then you are unlikely to be able to solve the problems already, and the specialist's help is needed.
