I had the problem that I got the warning despite deactivated adblocker. The steps from the support and from various posts have not helped.
1.0 Follow the steps from the support (https://support.aternos.org/hc…ou-are-using-an-adblocker)
2.0 Use another browser (e.g. Edge) without add-ons.
2.1 If the error persists there: Check your anti-virus and your internet connection again.
2.3 Try to open Aternos on another device in your network (e.g. Smartphone / Tablet) to exclude webfilters
2.2 Do you see ads on other pages?
2.3 Are you using any other software? (AdGuard, PiHole, ...)
2.4 Change your DNS to 126.96.36.199 / 188.8.131.52 / 184.108.40.206 / 220.127.116.11
3.1 Check if your add-ons are allowed to access private tabs, if yes: remove the permission.
3.2 Open Aternos in your default browser in the private tab, if you see ads everything works fine and you can coninue
3.3 Reauthorize add-ons one by one, refresh Aternos with CTRL+F5 (Important: not only F5)
3.4 If you don't see any ads you have found the add-on that causes problems: Try to deactivate it for Aternos.
3.5 For me it was the add-on "I Don't care about cookies".
Please share your solution if you found others.
Maybe the mods can leave this post open.
