Safari and other programmes do not connect to the internet, update servers etc.

The problem consists in the following things:

  • Safari cannot load websites
  • MS Office programmes do not connect to the internet (cannot update, cannot use OneDrive)
  • No access to the AppStore, MacOS Update servers (new updates cannot be found)


These problems appear in my WIFI network and other (mostly private) networks, however the problem disappears when I start using the University VPN (Open VPN). When connecting to the VPN, the programmes can access the internet flawlessly.


What I already tried to solve the problem:

  • Update MacOS to Big Sur 11.2.3
  • Uninstall basically every third party programme besides Opera Browser, MS Office, Open VPN
  • Erase Caches (Deleting files under "~/library/caches" in the Finder)
  • Reset PRAM and SMC



MacBook Pro 13″, macOS 11.2

1. Deselect Proxies, if selected.


   System Preference > Network > Advanced  > Proxies Tab

   Unlock the lock if you have to.

   Under "Select  a protocol…”, uncheck any box if check-marked.

   Click "OK” then  "Apply”.
