Hi,
I have couple of tenants and dont see any issues, what happens when you click the connect workload to the workspace from the Log Analytics console? Are all the servers in same Resource Groups and VNET? Can you check the troubleshooting steps and follow the process to analyse the server - https://learn.microsoft.com/en-us/azure/azure-monitor/agents/agent-windows-troubleshoot
Hope this helps.
