Chat+ error

did a fresh install of centos 7 and the Rocket.Chat - but now getting the following error:

Exception while invoking method 'login' Error: Failed to fetch identity from cvp71 at http://cvp71.com/m/oauth2/api/me. failed [401] {"error":"invalid_request","error_description":"Only one method may be used to authenticate at a time (Auth header, GET or POST)"}

Looks like it thinks you are already logged in via dolphin perhaps or as the chat admin for what ever reason...  

Just a guess.. 

i logged out of both - and after it logs into dolphin - then i get the error - when it tries to send info to chat server
