USPS Tracking not Working

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:

Thank you for contacting the USPS® Internet Customer Care Center.  You have reached USPS Technical support. I apologize as I have no additional information currently. This service offers limited tracking and is not supported by the inquiry process.

                3. Enter the Tracking Number of your package then click "Next".
                4. Please fill out the form with as much information as possible

                6. Select “Finish”
                7. Please review your information and click “Submit” if it is accurate.
If you, the recipient, DO NOT have the tracking number from the mailing label or receipt, please contact the shipper. If you were notified by a shipper that they have sent out a package and believe it has been delayed or possibly lost, contact the mailer of the item, and request them to:
                • Provide the tracking number, or.
                • Track the package
Please note if you are not located in the United States, you will need to contact the Postal Service in your country for tracking information.

The good old tracking service is gone.

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

Too, I've found the good ol' website will, sometimes, not give me ANY opportunity to login! That long line appears at the top of the screen reading, "You do not have permission...." When this happens, and you may have to click on this link several times to get it to open, I go to Google, enter "USPS" and "usps tracking" appears. I click on a lower link, "Where Is My Package." Go down to "Customer Information," click on "tracking status of your package here." THIS will open the good ol' tracking website and ALWAYS SIGN-IN FIRST! THEN...you can track a package! Once you have tracked your package and see the results, ALWAYS, ALWAYS, ALWAYS...click "Text & Email Updates!" Sign-up for this and you will NOT have to keep tracking the package!

Thank you for these Links, they work fine! I am having the same issue and cannot use the regular USPS Tracking, all I get is a white page and I am using Google! I hope whatever the problem is gets fixed as its been a while since it has worked!!
