Web page card - suddenly "refused to connect"

Configuration Frontend
1

I’m using https connection to HA and I can access standalone Grafana via https in a separate browser. I had a dashboard successfully showing iframe embedded graphs until very recently.

Suddenly, dashboard is showing “refused to connect” ???

Something has changes with recent updates??? Help please.

You have to look at your log-files, not just the Log-View, but to the right of, the 3 dots RAW-Logfile

OK… so looking at raw now… to be honest, I’m not sure what I’m looking for… :frowning:

any hint on how to refresh dashboard request and what to look for in raw log?

EDIT: “net:: ERR_BLOCKED_BY_RESPONSE” ???

Everything was working perfectly until very recently. very confused.

Well, basically, ERRORS or Time-out or Connection- type logs, use to have red-colors

But as you don’t tell anything in regards to what you have tried/done, maybe it would be best if you first Rebooted your HA-Device

well… fixed… Something seems to have changed with my NPMplus proxy??? Everything was working and suddenly I needed to add the following to the custom settings for the Grafana proxy host:

add_header Content-Security-Policy “frame-ancestors ‘self’ https://ha.yourdomain.com”;

I’m not sure what changed. If anybody has any insight, I’d be keen to understand.

Thanks.
