new toilet leaking at waste outlet

[geojul]

I am fitting new toilet and when i conect to waste out let it leaks , just slightly a few drips from around where the rubber connector fits onto spiggot on back of toilet. I have replaced the rubber connector with new one and even tried three different makes of connectors but all have the same outcome, will not form a watertight seal with toilet. any ideas?? is it possible toilet is faulty??

Put a ring of silicone sealant inside the pan connector.
