Install AMA on Azure arc enable servers not working

Hi,

I'm try to install/setup AMA on azure arc enable servers but it mailing to start MonAgentManager.exe after 480 tries

Our Config

• Gateway server (All firewall ports are allowed)
• All our Azure Arc server which have AMA agent install should be talking to this gateway server to send all logs to azure

Done following

• Install Azure Arc on all server which will required AMA
• In Azure Arc under server -> Extensions I can see "AzureMonitorWindowsAgent" Succeeded
• In Data collection Rules -> create new rule and server is showing under this rule
• Link all policy to this azure arc enable servers
• On-prem server I can see "C:\Resources" & "C:\Packages\Plugins\Microsoft.Azure.Monitor.AzureMonitorWindowsAgent\1.29.0.0"

Error

• On ama server I dont see "C:\Resources\Directory\AMADataStore\mcs\mcsconfig.latest.xml"
• On ama server MonAgentCore.exe process is not running

Question:

• For Proxyaddress which address is use Gateway server address or proxy (All of the logs are transfer from gateway server)
• How do you change proxy address if I need to?
