Windows timeout to websocket Chrome to short

[BasvanH]

Hello,

We are using rather slow Celeron Intel nucs for our Grafana screens. Sometimes, the startup is to slow and grafana-kiosk stops with an error. It would be great if this timeout could be extended or settable.

Having the same problem on a slow pi. Any way to fix it?

We applied a work-around by delay starting the kiosk. But this requires a settable option to fit all needs.

Had this problem too. For me it was solved by installing rng-tools via apt install rng-tools.

chromium-browser took ages to load after upgrading to the latest version because the random module was missing entropy. it blocked to start chromium until enough entropy was generated.

By installing the mentioned package, this was solved.
