401 - Unauthorized: Access is denied due to invalid credentials - API places/microsoft.graph.room

Hello, my app start to face issues trying to call this api -> https://graph.microsoft.com/v1.0/places/microsoft.graph.room
we are getting this error:

{
"error":{
"code":"UnknownError",
"message":"<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \" http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"">rn\<html xmlns=\"" http://www.w3.org/1999/xhtml"">rn\<head>rn<meta http-equiv=\""Content-Type\" content=\"text/html; charset=iso-8859-1\"/>\r\n<title>401 - Unauthorized: Access is denied due to invalid credentials.</title>\r\n<style type=\"text/css\">\r\n\r\n</style>\r\n</head>\r\n<body>\r\n<div id=\"header\"><h1>Server Error</h1></div>\r\n<div id=\"content\">\r\n <div class=\"content-container\"><fieldset>\r\n <h2>401 - Unauthorized: Access is denied due to invalid credentials.</h2>\r\n <h3>You do not have permission to view this directory or page using the credentials that you supplied.</h3>\r\n </fieldset></div>\r\n</div>\r\n</body>\r\n</html>\r\n",
"innerError":{
"date":"2022-06-21T14:21:50",
"request-id":"f8f6a53c-114a-41a4-b267-22a09bc66561",
"client-request-id":"f8f6a53c-114a-41a4-b267-22a09bc66561"
}
}
}

The app was working fine until last week but start to fail. Unlucky we were researching in Internet and try a lot of workaround but get the same error every time, we registered a new app in azure portal (generate new clientid, secrets).
We were trying enabling delegate and application permissions -> Place.Read.All, but we got same error in both cases.

About token we are using DelegateAuthenticationProvider with next function:
var result = await app.AcquireTokenForClient(new[] { " https://graph.microsoft.com/.default" }).ExecuteAsync();

Token is generated correctly but once we send the request to get places api we received the error above.
This is the token information:

From which user account are you trying to access this endpoint (global admin /user account)?

Please try to recreate this issue using Graph Explorer by login in with the same user account and share the screenshot of the response.

Hi @CRISTIAN HERNANDEZ ,

Since the issue seems to be user specific and inconsistent, I would recommend you to raise a support ticket from Admin center. You can add error message along with request ID and time stamp in the issue description while creating the ticket.
