Better results and less #¡VALUE!

I don't see any request to Ahrefs. Perhaps you have cache enabled? If so, disable it.

I see everything except calls from Excel. Does this make sense?

As you can see in my example, the Ahrefs request is visible. Perhaps this is because you have some kind of firewall or network setting/protection. Can you try and disable as much as you can then try again?

Sorry, I'm still trying. I have everything disabled but I don't see requests from Excel or the Apis neither from other applications like Scrapebox. Only Google Chrome

Do you have someone who can inspect your computer/network settings IRL?

Not really. Any link for further info?

By the way: I have the problem at home and in the office. So its a problem of the computer not the connection right ?

Probably if it occurs in two separate locations. Sent PM about further inquiries.
