Fidelity "The page you requested is currently unavailable." during 1099 download process (success)

2023 Turbotax Desktop Premier downloading Fidelity 1099 info.

I got to where TT said it would connect using my default browser. Fidelity login did come up in my default browser.

I did enter my login credentials into the Fidelity window. I got

 

"The page you requested is currently unavailable. Please try again later."

 

The TT-launched intuit.com browser window said


"Fidelity Investments
We couldn't complete your connection.

Try again or go back to select a different account provider. (571)"

 

I went back to TT and tried again and again. Nope.

My suspicion that some setting I made on my default browser was interfering with the operation.

My workaround was to temporarily make a different browser my default -- a browser that I had not tightened up and still used total defaults.

Going back to TT, after a few times just telling TT to try again, I went back to an earlier point in TT. This time it worked. Launched a Fidelity login into my temporarily default browser. Got the message that the info had been downloaded. Success!

I followed that by deleting cookies and history from my temporarily default browser. I went back to my usual browser, and made that the default again.
