I did test it now.
I get the same result, If I use the mac address from your example. Though, if I use a different mac, it indeed works.
I used: 02:42:05:96:eb:99 and it worked right away.
It depends on the mac address whether it works or not:
10:ab:98:82:eb:51 → ok
11:ab:98:82:eb:51 → error
12:ab:98:82:eb:51 → ok
13:ab:98:82:eb:51 → error
14:ab:98:82:eb:51 → ok
15:ab:98:82:eb:51 → error
16:ab:98:82:eb:51 → ok
17:ab:98:82:eb:51 → error
18:ab:98:82:eb:51 → ok
19:ab:98:82:eb:51 → error
1a:ab:98:82:eb:51 → ok
1b:ab:98:82:eb:51 → error
1c:ab:98:82:eb:51 → ok
1d:ab:98:82:eb:51 → error
1e:ab:98:82:eb:51 → ok
I have no idea what makes it a valid or invalid mac address…
Update: so apparently you can’t use every random mac address, see: networking - What exactly are the specifications for a valid mac address? - Super User
You can assign any hexadecimal character to every position of a mac address, except the 2nd character in the first block, like the example from above shows.
