Problem with oAuth & API Key for Grafana WorldPing Account

Dear Community Hello,

I faced some authentication issues and trying to troubleshoot that i deleted and re-created API keys and oAUTH keys from account as i thought that this action whould resolve the problem.

After that actions i cannot log-in @ instance taking error messages for authentication

I try also to modify URL with new cliend_id but it failed (check printscreens attached)

Could you help me if any action can be done before i deleting and re-creating WorldPing instance from scratch?

I Use Free account on Grafana Hosted Cloud and not any personal or virtual server of my own.

Thanks & Regards,

Dimitris Vampoulis
