Gmail not linking in outlook live

[needhelp25]

Yesterday my gmail stopped updating in Outlook on the web so I removed the account and when I've tried to re-add the account, I'm receiving the below error message. 

500

Something went wrong.

An error occurred when you tried to access your mailbox because a  server with information about you and your mailbox couldn't be found.

Does anyone know how to fix this?

Hi first clear your browser's cache and of course do the update and restart your computer.

@Andrzej1 Thanks for the reply! Unfortunately that didn't work. I tried on a separate computer as well and am receiving the same error message.

Please check if you have a 16 character password and 2FA authorization enabled in your Gmail security account and then try adding gmail account to Outlook
