Hello @All,

we're using transparent proxy for some update servers.

On Windows with browser, a download of files is possible.

On Linux shell with curl like (curl https://the.earth.li/~sgtatham/putty/latest/putty-0.77.tar.gz) it is not possible.

Message:

curl: (60) SSL certificate problem: self signed certificate in certificate chain
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

 

Also, we have one other problem on Windows also with transparent proxy to get updates from Virus scanner software over the internet. The site for updates are visible from the Browser, but not from the application. both on same machine.

 

Many thanks for helping

I have now made some progress by installing the FGT certificate on the Linux system.
With it Curl worked.
Unfortunately, this did not work on the Windows server.
The question is, why is this FGT (FGxxxxx) not automatically integrated on the systems, but declared as untrusted. How can I solve this problem?
