Internetbox Admin website cannot be loaded

I received my internet box today. I actually wanted to access it offline via the Web-IF. Unfortunately, I receive a message that the site cannot be reached. All of this under Win7. A ping works perfectly!

Now I started a Grandpa XP on the same configuration. Lo and behold, I get the admin pages and can make changes.

Even from a Win7 laptop, the admin page cannot be started.

There are no functional differences between the browsers either, at most the error messages differ, but factually they say roughly the same thing for IE11 and Firefox.

My suspicion was that the Ethernet config must be wrong somehow, but without deeper knowledge I can’t identify the crucial parameter among the countless.

Maybe there is actually a crack here that can give me the decisive clue.

Thanks

Thank you very much for your tip. Unfortunately, I couldn’t find the item regarding firewall in Kaspersky AV. However, I have disabled KAV, with zero success. So I uninstalled KAV and the admin website works again.

After reinstalling KAV it still worked. But a few hours later the same thing happened again; Error loading page.

I have now opened a ticket with Kaspersky. It can’t be that I keep uninstalling and reinstalling KAV:smileymad:
