I come back to an open tab on my browser (android chromium) after some days. I need to login again. Try and login with my user name and password. Try and login wifh user name and password and get a "Not allowed Invalid CSRF token" fail screen

I goto the playground bonfire home page and try again and see the second error message. Finally i succeed by using me email address rather than user name (i was using @ at beginning of user name)

(Trying to repost this without the attached images, Ill add them to the next post, as I couldn't see the post button with them attached - also the X to cancel the post didnt work or the delete attachments so i had to reload to be able to write a new post)
