whats is -1008f

See this Apple article for details:

If your Mac starts up to error -1008F - Apple Support

That error indicates some sort of an issue with your network connection. Try connecting the Mac directly to the router using an Ethernet cable and any necessary adapters for a faster more reliable connection which bypasses hard to troubleshoot WiFi issues.

Try power cycling your router.

Sometimes it can even be a router setting or configuration issue, or an ISP issue (you won't be able to do much about the latter though except try Internet Recovery Mode at a different location which uses another ISP).
