Hi Nils,
We're glad to look into this & help you.
Please clarify the last action that you've performed before the issue occurred. Meanwhile, please try clearing your browsing data & then attempt to visit the site in an incognito mode (in private browsing).
Additionally, check & ensure that the date & time is set correctly.
If you suspect that AVG is causing the issue, you can disable AVG protection temporarily to check.
All of a sudden today I get this message if I try to open a number of websites (common ones I always open) on either Chrome or Edge. I can't get to the sites and wonder if anyone has an answer. Thanks.
