You can use ClassMethod ##class(Ens.Util.Lookup).UpdateValue(pTableName As %String = "", pKeyName As %String = "", pNewValue As %String = "", pCreate As %Boolean = 1)

This will update the value of an existing entry with the supplied TableName and KeyName. If pCreate is true, then the entry will be created if it doesn't already exist

Have you tried defining a port, I've run into similar issues before when the server string did not contain a http:// prefix and no port was defined.

Thanks
