Hi @David_Ford
I enabled diagnostics on your Core, and the first thing I notice is that there are a lot of networking errors, specifically DNS errors. I’d recommend setting your router to use Google or Cloudflare DNS and see if that helps.
I also wanted to note our policy on Innuos Cores, and would recommend trying out a different Core on the same network after changing DNS if there are still issues. Does a different Core exhibit these issues?
