I tried werkzueg 15.0 and Werkzeug==0.16.1 versions still getting the same error

My primary sub-domain intranet.domain.in is showing 404 error and other sub-domains are showing a fresh odoo select database page.

I think the database connection failed due to some issue with the werkzeug.

Please help me to fix this issue.

Hi, 

Try: pip install "werkzeug==2.3.8"

It is the most stable with Odoo 17.

I work by updating Werkzeug to version 2.3.3 in Odoo 14 and then restarting the server

pip install werkzeug==2.3.3

Hi,

As per this solution:  https://www.odoo.com/forum/help-1/attributeerror-module-werkzeug-routing-has-no-attribute-numberconverter-207496 it says 0.16.1 version of Werkzeug will resolve the case.


As you said that you already have installed it, can you confirm that you are using the same python environment in which you have installed the package. There is cases, people will install packages in default python version and running odoo with using diff. python, ie using venv , can you confirm the same in your case. Also once package is installed, make sure to stop and start the service.

Thanks
