Thank you for your reply.
It was a painful lesson.
I would like to see a small change to the page about self signed certificates.
My device does not have a smartcard so the whole description simply does not work. The solution is quite simple and straight forward:
Simply put the certificate as .crt (not .cer) on a webserver and then download it from the browser in your device. The certificate is directly installed then.
(So quite easy and straight forward!)
So maybe you want to add this information on that page. (It would have helped me because I was searching the net for quite some time to find this solution!)
With kind regards,
Thanks for the suggestion, I have merged this into the Configuration page.
