Web sites deployed on IIS will become inaccessible after running for a period of time

Question

I deployed some websites on IIS. After a period of time. These websites cannot be accessed normally through domain name. Message :"The server IP address of this URL cannot be found"。When this problem occurs, the server can access the website normally, and after the server accesses the website normally. It will return to normal. I want to know what may be the problem?

Hi @yu zhao,

When you visit a website by typing a domain name into your browser, the internet tries to translate that domain name into the IP address of the server where the site is hosted, and it does this through the Domain Name System (DNS). Message : "The server IP address of this URL cannot be found" This error indicates that the DNS lookup process was unable to find the IP address for the specific domain name.

This error can occur due to a slow or unstable internet connection causing problems opening the website; or a caching issue; or a DNS server shutting down abnormally. You can troubleshoot by:

• The stability of the Internet can be verified by launching another application or opening a website.
• Try clearing browsing data as it clears any old cookies, settings and other cached data that may affect your browsing experience.
• Try to refresh the DNS client service or restart your DNS service.
