400 Bad Request

[AlHarvey]

Why am I receiving 400 Bad Request while trying to log in to shawmail?

@AlHarvey  Works for me, try again.

@AlHarvey -- close all instances of your web-browser. Shutdown/restart Windows. Try again.

What does that mean? "Close all instances of your web browser?"

If you look at the Windows "taskbar" -- by default, it is positioned on the bottom of the screen, do you see more than one icon for your web-browser, or overlapping icons?  If so, right-mouse-button click on one icon, and choose "close".  Repeat for each other instance.

Note the overlapping icons for Microsoft Edge. That indicates that you have multiple instances.

I've been getting the message below when ever I try to access Shaw Webmail on my PC. It does not happen on my Android. And yes, I'm connected to the internet, I've shut down many times as this has been going on for months.
"400 Bad Request Request Header Or Cookie Too Large nginx/1.24.0 "

@chuber -- when I get the same error-message, I close all my web-pages, restart my web-browser, and try again. This deletes some "session cookies" that are rucking-up your logon attempt.

Some web-browsers will show you a list of "cookies" that it has saved, grouped by domain-name.  If so, scroll through the list, and delete just the cookies that reference "shaw.ca".  Then, close/re-open your web-browser.

I have cleared the cookies/cache and as I said, restarted my computer many times. I'm not the only one with this issue, so it's not my PC. It's a Shaw/Rogers issue. Why it affects only my PC and not my Android, is odd, but maybe Shaw/Rogers has some thoughts on users having to change a setting? Or maybe they have to?

@chuber Which browser?

I'm reminded of "poor workers blame their tools", but this probably does not apply. 😞

Two completely-different operating systems that probably do not handle "cookies" in the same way.

Try closing all web-browser windows. Open just one, and use "manage cookies" to delete all cookies related to the "shaw.ca" domain. Close the web-browser. Restart Windows. Try again.

Welcome to this peer-to-peer discussion forum, where volunteers try to help.

In the past few years, I have not seen any postings to this forum by Shaw employees. I doubt that any of them is monitoring this forum, except for a "moderator". I doubt that they have authorization to make postings using their "handle" which identifies them as an employee.

Bottom line: you can "wonder" -- like shouting into the darkness -- or you can contact Support [1-888-472-2222]. You'll probably get "canned" advice --> "try a different web-browser" or "reinstall Windows" or (stupidly, since it never helps) "clear your browser history". Sift the wheat from the chaff.

Hint: if you want to repeatedly get an error-message, enter:  https://webmail.shaw.ca? 

Yes, adding the "?" is the trigger. When talking to Support, get them to enter exactly this URL on their computer, if you want to puzzle them.   🙂
