Domain name resolution error means that there is an error in DNS and the domain name cannot be correctly identified, so the corresponding website cannot be opened. Internet users often use domain names to access websites. The system must convert domain names into IP addresses in order to correctly access the correct website content through routers at all levels.

Domain name conversion is usually done by DNS (Domain Name Resolution Server). But sometimes users will find that they cannot access the correct content even after entering the correct domain name. In this case, there are generally two possibilities. One is that the website fails and stops running; the other is that there is an error in domain name resolution.

1. Website space problem

If you check the relevant A record, MX priority and host record There are no problems with the pointing, and the domain name has been successfully registered, but if the website still cannot be opened and the domain name shows a resolution error, it is likely that there is a problem with the website hosting space.

The stability of the website space will affect the Internet link, making the corresponding domain name unable to correspond to the IP address of the host space. If this situation is reflected in the error form, a parsing error will still be displayed. Therefore, it is necessary to analyze the quality of the website space at this time. If the space is not stable enough, it is best to replace it in time, or ask the hosting provider to solve it.
