Pressure canner not sealing.
I'm using a pressure canner, but it seems the steam is coming out around the lid. Not sure if it has a good seal? and will the jars be ok for eating.
If the pressure is not building then your jars will not be sterilized.
I'd suggest turning the canner off. If there is any pressure let it release itself then carefully remove the lid (always tilt it away so steam doesn't hit you in the face). Check the seal and see if it is twisted or dirty or anything. Then try it again.
If it still won't seal you may need to buy a new gasket.
If it does seal then be sure to start your time over for your food. It needs to process for the entire time suggested.
I hope that helps.
