Admin panel 401 error

Please, I need help with the same error, but I have already deployed my project on AWS. The project has been deployed successfully and is working fine. The problem I am facing is that I want to access the admin panel to add more properties, but I encounter the following issue:
Failed to load resource: the server responded with a status of 401 (Unauthorized)
{
“data”: null,
“error”: {
“status”: 401,
“name”: “UnauthorizedError”,
“message”: “Missing or invalid credentials”,
“details”: {

}

}
}
Please somebody can help me ?
