@GoodGuyQ My guess is you’re entering the wrong user/password. You can add a new user in the webgui to test that out.
Here is my quick image item for reference
set username foglogin
set password foglogin
params
param mac0 ${net0/mac}
param arch ${arch}
param username ${username}
param password ${password}
param qihost 1
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
With foglogin being a valid username and password
