All ReadyNAS use self-signed certificates, so you will either need to add the exception, or click through the browser warning.  The connection is still encrypted, the security concern is that a man-in-the-middle attack is possible (a server that somehow gets between your client and the NAS could also use a self-signed certificate with 192.168.2.25 as it's IP address).  It's not a concern on your home network, but could be if you access the NAS over the internet. 

Personally I don't recommend allowing internet access for a legacy ReadyNAS anyway, since it is no longer receiving firmware updates with security patches.

 When my ReadyNAS is connected  to the  switch of my internetconnection at first LAN input of my PC , 192.168.2.xxx  too, I get the Following Message.

Error: Connection failed

Likely the PC IP address for that LAN port is misconfigured. Another possibility is that the NAS is using DHCP, and is failing over to a different IP address when you directly connect it to the PC LAN port.

Can you give us more information on the connection path?  What IP address is the PC using for that LAN port?  Also, check with RAIDar, and tell us what IP address it is showing for the NAS.  https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar
