Hi,

If you could please send along the URLs you are getting the 400 messages on, we'll investigate.

Hi,

Please go to https://seekingalpha.com/clean and login again. 

Cannot go to that address. When I type it in, I get the 400 Bad Request page.

Uninstalling the app, and reinstalling the app seems to have worked for me.  iphone SE with latest IOS and latest SA app

I have this issue too!

Gray67, are you having the issue on the site or an app?

Same problem with Win 10 for days.  Closing then logging back in fixes it for a short time then the same error!

Apparently you did an update this weekend   I received a notification over this weekend that your site was "unavailable" so you could "improve" the site.

Same issue on my desktop for the past 2 days.

I am running Windows 7 Home Premium and Chrome browser.

I can clear the Cookies and be able to click on, maybe, a couple of email links and have them work, then it goes right back to the 

400 Bad Request

Request Header Or Cookie Too Large

nginx/1.8.0

ditto here as well. running Chorme on windows 10

only happens when linking from email notice

happens to me on my iPhone all the time. I like SA but it’s the worst apple app I’ve ever used.

I think I should just quit commenting.
