try changing the DNS server. I had a similar issue that was related to the last update but with different update category (in my case only the security definitions would not update) changed my DNS to Google DNS server and it worked. Still on their DNS with not issues on my SE.
I have the same model of Lapbook SE i.e. 64 GB eMMC variant. Yes the type for the SSD is M.2 (also referred to NGFF) 2280 size just I case you are unsure as there are 2 types and can confuse people. The connection has the 2 notches as a visual clue. Hope this helps
