Error when setting password - Feature not implemented or unavailable under current execution privile

"need a password" for what?

The help doesn't really help...

JTAG Server Configuration

Usage: jtagconfig [--enum]
jtagconfig --add <type> <port> [<name>]
jtagconfig --remove <cable>
jtagconfig --getparam <cable> <param>
jtagconfig --setparam <cable> <param> <value>
jtagconfig --define <jtagid> <name> <irlength>
jtagconfig --undefine <jtagid> <name> <irlength>
jtagconfig --defined
jtagconfig --addserver <server> <password>
jtagconfig --enableremote <password>
jtagconfig --disableremote
jtagconfig --version
jtagconfig --help
jtagconfig --extrahelp

For more details use jtagconfig --extrahelp

And for enableremote:

--enableremote Tells the JTAG server to allow connections from remote
<password> machines. These machines must specify the same password
when connecting.

As you can see in the screenshot, the password is provided "mypass".

Then, why do I get this error message?

As you can imagine, I follow this page: https://www.intel.com/content/www/us/en/docs/programmable/683472/22-4/installing-and-configuring-a-local-jtag.html

Thanks.
