Arduino IDE behind a proxy: unable to download controllino board

[nicokid]

Hi,

It is the first time I use Controllino, currently I have only used Arduino UNO and DUE. I use Arduino IDE 1.8.12.

I was able to install the software libraries without problems, but unfortunately I cannot install the hardware libraries.

My company is using a proxy to access the internet. I tried setting the proxy in the Arduino IDE and I added the link https://raw.githubusercontent.com/CONTROLLINO-PLC/CONTROLLINO_Library/master/Boards/package_ControllinoHardware_index.json in “Additional Boards Manager URLs:”.

The rilevant error is:

java.io.IOException: Unable to tunnel through proxy. Proxy returns “HTTP/1.1 407 Proxy Authentication Required”. I put username and password in settings but it doesn’t seem to work. 😥

Anyone know how to fix this?

Thanks.

I answer myself: Arduino IDE 1.8.12 does not save the login credentials for the proxy. I think it’s a bug.

I had to configure my proxy server to make access to raw.githubusercontent.com free without any user and password.

Unfortunately I have not found a better workaround.

Nicola.
