Content Manager AxiosError

I deployed my strapi 4.20.0 application with a reverse proxy, but when I log in to the panel, I click on the section where I will manage the content and the places to enter the content do not appear and it returns an error in the console.
Console Issue details:
Message: “Request failed with status code 400”
Name: AxiosError (Error coming from the Axios library that Strapi uses)
Request URL: /content-manager/content-types/api::about.about/configuration
Error Code: 400 (Bad Request)
