Unable to open Analytics UI intermittently

Hi Team,

We are using Weblogic 12c on Windows 2012 R2 and getting below error. We are using Edge and Chrome however sometime it does work. We opened case with Oracle but seems we are getting nowhere. Can someone help? Thanks in advance. Does it have anything to do with Windows patching? The Weblogic servers are patched till Oct'22 and the DC's are patched till Dec'22, not sure if that helps.

Error 401--Unauthorized

The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.46) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity MAY include relevant
