Problems filling in tax information " An extension blocked the requests to the server."

[#1]

When I want to fill in the tax information, and I put the option of a country with an agreement in the United States, when showing me the filling sheet it appears to me that "An extension blocked the requests to the server." and I don't have any extensions or anything like that, I already uninstalled the extensions, I restarted the pc and nothing, is it a page error? I already tried several browsers and on my phone and it won't let me fill in that section.

Same to me. I tried different browsers (Chrome, Opera) but nothing worked.

The page wants to load a PDF, but something is blocking or maybe an error on server side.

PLS help!

Same! Tried deleting browser history and caches and didnt work on chorme.  Switched to safari with no luck, doesnt load or even show the error message.

Sorry about that, there is an issue on our end that we should have fixed later today.
