I’m having some trouble getting a couple of PVR Add-ons to install from the coreelec repository. I dug into the logs and found where the add-ons.coreelec.org/9.0 site was giving a 404 error. So I plugged the URL into a browser to make sure it wasn’t my box (Minix UH-9).
Long and the short is I think the addon site is down and didn’t know a better way to check on that. I’m at work so don’t have access to logs but can get them up this evening if it turns out to be something else.
