Homebridge fresh install
### Current Situation

Hi all, I recently started using homebridge on a Raspberry Pi 4B. I got it working allright, but in my innocence/negligence/stupidity I screwed something up after I rebooted my TP-Link Deco system.

So when nothing else seemed to work, I formatted the SD-card and made a fresh install of the Homebridge image - but unfortunately, it seems even worse than it was before. I still get this log all the time (as it did just before I reinstalled): [Homebridge UI] [homebridge-config-ui-x] Failed to check registry.npmjs.org for updates: "timeout of 10000ms exceeded"

But now I can't even install new plugins. When I search for a plugin, this is the (similar) message I get: 
Failed to search the npm registry - "timeout of 10000ms exceeded" - see https://homebridge.io/w/JJSz6 for help.

My internet connection is fine, so I have no idea where to look, and things like DNS are still complete gobbledygook to me, so I have no idea how to proceed... Should I throw the Raspberry Pi in the trash en buy a new one? :)

I'll add the debug log. Hope someone can help!
