I'm using a Rp3b (raspbian) to send pictures to weather underground every few minutes. It has been working great for a few weeks but stopped a few days ago. When I run the bash script that sends the image (via ftp to HOST='webcam.wunderground.com' I get this in the log file:
ftp: connect to address 54.148.11.124: connection timed out
Any ideas what the problem is?
