Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error

HI Everyone.
so I am using List.Generate function to extract data of unknow number of rows from an API but gives me this error after fetching all the rows.
PFB the URL:
URL: https://vcc-na8.8x8.com/api/stats/agents/{Agent-ID}/activities?n=

Error: Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] The remote name could not be resolved: ‘vcc-na8.8x8.com’


Let me know if someone has any idea about this and how to fix it.
