As for a knot with the ring, there are so many kinds. You can choose one that goes around the ring twice or three times.
The right picture shows the knot Sato Sensei makes, called “TN Knot”. It goes around the ring 3 times. He used to do only twice, but he figured that a 30 minute fight with a monster can wear it down, now he does this TN Knot.
Make sure the line does not overlap on the ring, wet the line before giving tying, pull the leader first and then the end to close it, finish with 15 half-hitches alternately on the leader (First 5 half-hitch with strong tension, then 5 half-hitches with medium tension, and 5 with soft tension. This is for not damaging the line with the line.), and burn the end.
For stronger knot, go into the loops for the second time. It requires more precise placements and stronger tension to make the tight knot.
Knots are most likely where it breaks. Make sure you are confident with your knots.
