Web interface not working

[kniven]

Hi. I have been struggeling with updating pypilot on my Tinypilot (Raspberry pi Zero) for some time.
I Updated the code from the repository (as explained here : https://github.com/pypilot/workbook/wiki...r-the-hood). 
Apparently Successfully built the code. Twice. 

The version now running is 0.52. The display on the pilot seems fine, and the initial problems I had (getting wind data into pypilot, also seems ok) Screenshots from opecpn interface and some debug info in the screenshots.

The issue now is the web interface.... See screenshot. Any suggestions to where to start?
Best regard, Leif

did you check the pypilot_web log? I see you have the console output from pypilot itself.. did you run it directly? If so you should consider running pypilot_web directly to find the issue, or check the log in /var/log/pypilot_web/current

Same issue when not running from command line.

This is the response when trying pypilot_web
