Access denied for one website (Re-Post; Still unsolved)

Have you tried clearing the caches and cookies from those browsers?

Give that a try and see if it helps at all.

It's common that some websites cannot be properly accessed by certain browsers.

Safari has trouble with some and it's not surprising that Firefox and Chrome might have trouble with others.

It all depends on the internet standards and protocols that the site developer adheres to when designing the site.

If those browsers worked before, then perhaps the site servers are having some trouble or a site update has been made and gone a little sideways.

Try accessing the site again in a day or two.

Don't let the ability to not access an IRS site by browser, stop you from calling them. They do answer their phones, and can probably help you right away rather than expecting us to remotely debug why you cannot access their site.

Duhh...of course I am. I've used it MANY times before.

And we're supposed to know that how?

I get the access denied message AFTER entering username and BEFORE password.

I missed that detail in your original post.

Are you using the correct address?

I can reach it in Safari, Firefox, Brave…
