Hello @typomike, Welcome to Linux.org.
A few of questions.
1. which version of ubuntu.
2. Give us more information on your setup Machine? Model? etc.
3. Is it WIFI? or Ethernet?
4. Are you using and VPN's or Firewalls?
5. Which browser are you using?

@typomike :-

Um; o-kayyy.....

Can you clarify further, please? Do I take it you can access some sites, but not others?

As @kc1di has asked, more information will help. The version of Ubuntu, for sure.....and which browser? Access to some but not others sounds like a certificate issue to me, but I could be wrong of course...


Mike.
