USPS Tracking not Working

I use Firefox.
Chrome, Edge and any other chromium-based browser give me the same error, randomly.

I think this has our answer. I emailed this question to USPS:

I have used https://tools.usps.com/go/TrackConfirmAction_input for years in tracking packages (and I receive MANY USPS packages!) and now, suddenly, this website will NO LONGER allow me to use this!  There are MANY people who cannot use this!  I an in a Microsoft discussion page on this issue.  Please yell me if USPS no longer supports this webpage.  THIS will take care of the issue!  But why, when I try to OPEN this link, EVERY TIME, I see this:  "You do not have permission to access this page If you have found this page in error, please contact support Reference:##############################"  or any other USPS tracking number?  Thank you.

USPS reply:

I had this same issue today. Going to a plan white page. Once I turned off my VPN, It worked fine. Tracked 3 packages with out any problems. Its still working but seems to be having issues with some ISP's

OOOOOOKKKKAAAAAAAAAAAYYYYYY!!!! Here's the latest! Tonight, April 23, 2024, I have 4 USPS packages in transit to me. I KNOW the rejection I have received with https://tools.usps.com/go/TrackConfirmAction_input, the website that NO LONGER WORKS! WELL...I got my CELL PHONE (YES, MY CELL (AN ANDROID!) and I pulled-up the web address that I just listed! I entered EACH OF THE FOUR TRACKING NUMBERS, OF THE CURRENT PACKAGES HEADING TO ME, AND ALL FOUR TRACKING NUMBERS WORKED PERFECTLY, ON MY CELL, IN TRACKING ON THE GOOD OL' WEBSITE!!!!! I REGISTERED FOR THE PROGRESS NOTICES WITH NO PROBLEM!!!! I guess there are just some draw-backs to having a desktop computer! The bottom line, I used my cell phone SUCCESSFULLY to sign-up for the USPS PROGRESS NOTICES!!!! What we have NOT been able to do for, at least, six months!!!! I hope this helps!!!!
