Can not login using tryton or sao


I can not login using tryton or sao, I receive the follow message:
ERROR session failed for ‘None’ from ‘’ on database ‘mydb’

But I’m using my user and password correctly.

I already updated the database with trytond but without success. I’m using 6.6.3.


It’s linked to this issue: Cannot login with Werkzeug==2.3.0 (#12234) · Issues · Tryton / Tryton · GitLab

You should install Werkzeug < 2.3.0 :

pip install Werkzeug==2.2.3
