I received an email which reads, “Your certificate (or certificates) for the names listed below will expire in 20 days (on 18 Mar 20 21:23 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.”
It then lists a bunch of addresses starting with: diaspora.keene.syncloud.it
And finally it tells me to come here for more information, a place I’ve never heard of but has my email and knows these web addresses.
A few years ago I bought a pre-built raspberry pi device that plugs into my router and operates as a mini home-cloud server using Syncloud or Nextcloud or whatever they currently call it. I am only minimally tech savvy, but was able to connect the device to my network and create a Nextcloud account on my PC linked to the device. Now I get this email and after reading through the forums and looking at walk-throughs, I know I’m in over my head.
Is this something that must be updated on the raspberry pi? Is there a way to do that with my windows PC? The device does not connect to the internet, it is only available on my home network. Should I even worry about this?
Complete noob with no clue
