Cert problems on Windows 10

Hello guys,

I'm struggling with certification errors on my ReadyNAS 102, which is running on Firmware 6.4.2.

First of all, I get certification problems, when logging into my ReadyNAS via webbrowser under Windows 10 64 Bit (1511 based). I tested it with Firefox 45.0 and with Edge. Both browser always claim a certification error. On one Windows 10 machine I could overcome the problem by addind an exception, on an other Windows 10 64 Bit machine (1511 based) this is not possible. The browser is not accepting an exception to overcome the certification issue. It does not make a difference, whether I try to access the ReadyNAS via https or http. The error message claims, that a certification subject name is xyz (dummy) instead of the target host name abc (dummy).

Today I wanted to install the app owncloud on my ReadyNAS and here I ran into similar problems. The log states the following error message:

isWebDAVWorking: NO - Reason: [CURL] Error while making request: SSL: certificate subject name 'xyz.local' does not match target host name 'abc' (error code: 51) (Sabre_DAV_Exception)

Owncloud does not work after that. I read thru the forum, but somehow I did not find anything solving my problem, but perhaps I did not understand everything.

Can anybody help me?

Regards,

Michael
