Health status page in Grafana is broken

[15:36:39] <sanurmen> frgladho: Do you know what's wrong with grafana? Health status page is asking for "InfluxDB" credentials and doesn't accept either them or grafana credentials
 [15:37:05] <sanurmen> frgladho: same is happening for aakeskim and tosaraja (on the CI team's monitor)
 [15:38:37] <sanurmen> frgladho: Other pages seem to work just fine and there are no changes in the health status page
 [15:38:59] <frgladho> sanurmen: no idea, I haven't done anything  - the health thing only works for logged in users
 [15:39:17] <sanurmen> frgladho: logout/login does not help
 [15:39:31] <sanurmen> frgladho: and it appeared to all three of us simultaneously
 [15:39:56] <sanurmen> frgladho: Maybe auto-update did 
 [15:40:15] <sanurmen> frgladho: Is it working correctly for you?
 [15:40:39] <frgladho> nope, so probably the lastest grafana update messed something up indeed
 [15:41:42] <frgladho> sanurmen: well, the connection to infuxdb for the user fails

 [15:42:29] <frgladho> sanurmen: so to fix this, the telegraf datasource needs fixing (https://testresults.qt.io/grafana/datasources/edit/7)
 [15:43:10] <frgladho> sanurmen: can you please talk to dasmith and anwojcie about that? they have all the needed admin rights, I won't be able to do it myself any time soon
 [15:43:16] <frgladho> might be worth a bug
