Solving Bad Request Errors on Google’s Gmail

Google Bad RequestIf, like me, you have been seeing a lot of “Bad Request Error 400” messages or perhaps the yellow bad to the top of Gmail saying “Oops… the system encountered a problem (#400) – Retrying in” then, like me, you will be similarly frustrated.

This only seems to have been an issue in the last few months and I am not sure whether it is just an issue with Chrome but whatever it is a really time sapping problem.201307184_090781-CapturFiles

The details that I outline below aren’t a permanent solution, I suspect that is only in the gift of Google but they will allow you to get back into your email.

These instructions will only work on Google Chrome.

Firstly, from the “Bad Request” page you must do a right mouse click anywhere on the page (see image below) and then choose “Inspect Element” from the pop-up menu.

A new scary looking panel will open at the bottom. Select the Resources tab at the top and then on the left hand side look for “mail.google.com” under the Cookies section.

This will bring up a new list in which you should look for an entry called “GMAIL_IMP”. Right click on this entry and select Delete from the pop-up menu.

You can now close this panel using the cross in the top left of the panel and refresh the page and you should be able to log back in.

    Experiencing the same problem for weeks now (OS X 10.8.4, Chrome), wondering if Google will come with a permanent solution…

  • Looking at the forums this seems to have been a problem for a while so I am not hopeful.

  • do you have to do this every time you log in to gmail?

  • @disqus_JWBlack:disqus the post is a bit old now (five years) so I am glad to say that I no longer see this. Are you seeing it?
