"Unexpected error" on home dashboard

I have just finished re-installing percona monitoring and management on a dedicated server.

After the fresh install, I went to the web interface, and all loaded fine.

Then, I configured the various mysql servers to connect to this monitor server, and all connections went fine.

However, now, when I load the main page of the web interface (the “home dashboard”) there is a small popup saying “unexpected error” and many of the charts just won’t load.

“unexpected error” isn’t too useful in diagnosing it … were should I look to understand what the error really is, and how to fix it?


I am using PMM version 1.17.1 and, although I tried to disable the upgrade using the option “-e DISABLE_UPDATES=true” in the docker run command, the upgrade check still seems enabled.
