Can't enlist target server for SQL Server Agent

Question

TITLE: Microsoft.SqlServer.Smo

---

MSX enlist failed for JobServer 'iris-wl-a301.tw01.ppanggu.com'.

For help, click: https://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=17.100.31.0&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=MSX+enlist+JobServer&LinkId=20476

---

ADDITIONAL INFORMATION:

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

---

The enlist operation failed (reason: The time-out was exceeded while the server waited for a response from SQL Server Agent. Make sure that the SQL Server Agent service is running) (Microsoft SQL Server, Error: 22026)

I already checked sql server agent is running, and service account is correct. Could anyone help me please, thanks.
