Trying to login to our grafana instance results in unknown application trying access our account

I’ve been trying to login to our Grafana instance from the Org-page, by selecting the “Details”-button and then login. However, I only end up with an unknown application trying to access the account. It’s an unknown application with an unknown URL. We have the option to Grant or Deny this request but from our perspective this doesn’t make any sense.

We have no option but to deny the request. What is going on here? It’s been replicated across different networks, computers, and so on. Also, I’m using a grafana.com-account with the hosted option.

2018-08-08: Out of nowhere things started working again the following day. No explanation to what or why this happened
