Sometimes, trying to open a website, user can

encounter the error message "Technical information: dnserror". The site itself refuses to load.


The cause of a dnserror or similar “Connectionfailure” error can be either a site failure or problems in the user's computer settings.

Specific causes of a dnserror error may include:

  • Website maintenance or failures in its functioning;

  • Domain name change;

  • Virus programs;

  • Unstable Internet channel;

  • Blocking of a specific site by an antivirus or firewall;

  • Blocking of a specific site by the provider;

  • the DNS server has a corrupted database;

  • The DNS cache on your computer is corrupted.

Methods for correcting the situation
