Problem accessing WebIOPi on web page

  • RPI Zero W- “Raspbian Stretch with desktop” - Release date: 2017-09-07

  • What dashboard are you using? (WEB)

Goodmorning, yesterday I installed my second RPI with cayenne, this time I used a RPI Zero W with a temperature sensor DS18B20.
Cayenne works perfect at all. I see temp sensor and data.

The only problem is I can’t login on the WebIOPi web page!
If I go with my browser on http://raspbery-IP:8000 I do the login with default password and all I see is this error message:

HTTP/1.0 500 Internal Server Error Server: WebIOPi/0.7.23/Python3.5 Date: Tue, 28 Nov 2017 10:45:05 GMT Connection: close Content-Type: text/html;charset=utf-8 Content-Length: 458

Error response

Error code: 500

Message: Internal Server Error.

Error code explanation: 500 - Server got itself in trouble.

I tried with different browser, but same issue.

Hi @andrea.mattioni,

It might be because Cayenne uses a modified version of WebIOPi. Tagging @eptak also.


I have not this issue on my other Raspberry B (512mb)
OS: raspbian 8 (debian)
Agent Version

I want to use WebIOPi like, on my other RPI with cayenne.
@eptak can you help me please? Hawe you see this issue on the latest release of Cayenne?

Best regards
