I setup Odoo Community 15.0 without any error messages.

after the installation the browser opened the adress: http://localhost:8069/

then the following Error message appears in the browser:

"Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."


Brower: IE or Firefox or Google Chrome ... all the same result :(

are there any requirements for odoo?

I also tried Odoo community 14.0 ... all the same! :(
