I have a valid IP on my MintyPi but am unable to sftp or ssh from my mac using filezilla or terminal. My error is "Conneciton timed out - could not connect to server." I'm also unable to ping the MintyPi's IP address. "Request timeout for icmp_seq 0,1,2,3, etc." I ran a lanscan of the network and also noticed that the hostname "retropie" isn't showing up either. I've checked to make sure ssh is enable in raspi-config and all is great. Still can't FTP.

I'm using the following in Filezilla:
Host: sftp://172.20.10.11 | Username: retropie | Password: •••••••• | Port: 22
Error: Connection timed out after 20 second of inactivity
Error: Could not connect to server

I also tried to SSH:
laptop:~ admin$ ssh retropie@172.20.10.11
ssh: connect to host 172.20.10.11 port 22: Operation timed out

So confused....

I was also able to successfully SFTP from filezilla just yesterday, but all of the sudden I can't now. Using the exact same username, password, and network.

after restarting the mintypi 3 times.....it works....

Could this be the onboard wifi crapping out on the pi zero?

<SOLVED>
Well for anyone interested I figured it out.

A little more background - I was having to use my verizon iphone to hospot a connection to the pi as my work network somehow blocks my ability to FTP or SSH. In doing so, I had my phone plugged in to the USB port on my laptop (so that I could charge it), but doing so actually messes with mac network settings and causes it to try and connected via USB tethering mode. I guess I still don't exactly understand why it didn't work, but the second I unplug it from my laptop - everything works and the hostname of the PI shows up. So weird...
