Problems with fetch command from router to a Shelly Plus Plug S

Hi guys,

we try to send commands from the router terminal to turn off/on an Shelly Plus Plug S. It is important that the shelly is password protected. Without password security the fetch command is working.

In the terminal of the router we tried the following different commands but without success.
/tool fetch url=“http://123.123.123.123/relay/0?turn=off” mode=http output=none
/tool fetch url=“http://admin:123456@123.123.123.123/relay/0?turn=off” mode=http output=none
/tool fetch url=“http://123.123.123.123/relay/0?turn=off” mode=http output=none username=admin password=123456


From an linux machine the communication is successful but with curl command:
curl --digest -u admin:123456 http://123.123.123.123/relay/0?turn=off

The shelly is wifi connected. IP-Address, user and password are adjusted.
Do you have any advise or tip for us?
Thanks in advance
