Are your cut and pastes of the details typo’s or are you using these invalid (based on your settings) copies?
To put a \\ you need to put 3 's in your post (see the right side edit preview) and I think capitalisation matters if you use the name so Diskstation and diskstation might be treated differently (don’t quote me on that) but IP address is safer and I assume its a fixed IP address in your NAS network setting too.
" \\92.168.2.115\muzi"
“\\Diskstation212\muzi”
Is this what you really have?
What OS is your remote using?
