Hi folks,
I have an Azure hosted machine which is unable to connect to Azure OMS to export Logs to Azure LAW. However, I am getting connectivity related errors in MMA config manager, Event Id 4001 in Event Logs etc.
Though, I have validated the connection between server and Azure endpoints, and it is all working on Port 443. Still, I am not sure, why is it throwing Network Connectivity errors.
Can anyone please suggest, any help will be greatly appreciated.
Additional info: I have tried reinstalling the Agent on the server, have renamed old config files but of no joy.
Thanks in advance!
Port 443 connectivity status:
Error in MMA:
TestCloudConnection results:
Event Id: 4001

2024-02-14T08:44:10.37+00:00 just an update.
Connection to *.agentsvc.azure-automation.net is not working on port 443, could it be possibly the reason of these connection errors?
Though, the error message says that it is unable to connect to *.oms.opinsights.azure.com and it is allowed and working as above snips. *.agentsvc.azure-automation.net connection:
Thanks for looking into this. Cheers!

From the Troubleshooting page: 4001 Service Connector Connection to the service failed. This error can occur when the agent can't communicate directly or through a firewall or proxy server to the Azure Monitor service. Verify agent proxy settings or that the network firewall or proxy allows TCP traffic from the computer to the service. Likely there is something in the network configuration or firewall blocking your request.
You can use the Connection Troubleshooter in the portal to see if there is an NSG or some issue blocking from the Azure configuration.If you are unable to resolve the issue please let me know and we can work with you directly to troubleshoot further.
