Hello, please excuse my poor English. Last year I asked for the same problem. I have my homepage: https://eberhard-koch.de/. When I'm using the Nu Html Checker almost everything is fine: Bildschirmfoto-7 But when I check for https://www.eberhard-koch.de/subtexte/google.htm the result is constantly: Bildschirmfoto-8 and that is the only error in almost 200 sites. Last time a staff member from your company wrote, that he's puzzled about this problem and that was it. But I'm puzzled until today. Can anyone solve this mysterious problem? With kind regards Eberhard Koch

As a workaround, please try something the following:

https://validator.w3.org/nu/?doc=https://eberhard-koch.de/subtexte/g%6fogle.htm

…that is, replace one of the o characters with its URL-encoded equivalent, %6f.

I’m sorry for the inconvenience and frustration this has cost you, but the cause of the problem you’ve hit is this: due to some persistent abusive/malicious use of the checker, certain code was added that special-cases URLs which contain "google". And the way around that when it causes problems is: replace part or all of "google" with its URL-encoded equivalent.
