Hello @Mati_chm,

Hello @Mati_chm,
Sorry for the inconvenience, it seems I cannot reproduce the issue. If you tried to logout and the problem continues I suggest to complete this form for a lab refresh. This is the AWS sign in screen I get:
Just logout and try again, this happens because it tries to use your own account or the previous account if you leave the AWS page open, just close the AWS tabs and logout and try again
