I want to know how to set proxy with username and password using azcmagent.

I successfully onboard my on premise server to azure arc. After that I tried to deploy some extensions like azure monitor agent to my server. My on premise server is using a proxy server with username and password authentication.

So I am trying using the command below. (By the way, the version of Azure Connected Machine Agent is 1.42.02699.1697)
azcmagent config set proxy.url http://myusername:mypassword@ipaddress:port

But I can’t deploy extensions and got following error in %ProgramData%GuestConfigext_mgr_logsgc_ext.log

Here are some links I refered.

The proxy and proxy port format seems to be some strange in the error message.
I want to know if my configuration is not correct.
Or some way to help me to solve this.
