When I am logged in I get a 403 Forbidden error switching from frontend to backend

[ermGit]

I am having a problem with getting a 403 error. I get the error when I do the following sequence: I login in the backend, view my frontend, and then try to return to my backend. On the screen that I get the forbidden error, if I click other backend links, I do not receive any more 403 errors. It just happens after I login in the backend and then switch from frontend to backend.

Mention your yii2 version and yii2 admin configuration
