Yesterday I set up influxdb and grafana following this guide.
Everything went well until some point (probably a ha restart?) i created a graph, imported it to lovelace etc.
Now im having problems.
Although i can log in in the main dashboard of grafana, whenever i try to either see a graph or create a new one, a browser log in window pops up.
I keep logging in there with correct credentials but it keeps repeatedly appearing.
If i enter wrong credentials grafana gives me red error tabs.
More than likely, you’ll need to update then re-enter all the passwords to save them correctly. Then you should be able to restart the server and it maintain the passwords.
Just in case this helps someone else… I thought I had the same problem, but I had the casing wrong in my InfluxDB username and it resulting in this popup when setting up the data source.
I was having the same problem but it was not relation with Grafana.
My NGINX reverse proxy was asking for password and fixed disabling this lines from my sites-availabled file (i have deleted ‘auth’ lines):
