There seems to be a problem with this app.
Error: redirect_uri_missing
Show Error Details
response_type=code
redirect_uri=http://127.0.0.1:53682/
state=<random string>
client_id=<random string>
Never mind, it started working as soon as someone else wanted to take a look... maybe there was a transient misconfiguration on box:s side?
To be clear, I tried the reconnect things for the fourth time today to be really sure I got the error details for the default case correct and now the refresh worked. shrug
