Multi Quick Joint Toilet Leak

[Castironproblems]

Hi,

I have a leak coming from the waste pipe of my integrated toilet that looks to be like the multi quick joint. It's at the bit between where the ceramic of the toilet meets a plastic pipe and there's some ruber in between. I watched a youtube video that recommends Plumbers Mait as a quick fix but was looking for some advice if anyone had the same problem

I'm looking for a easy fix as we plan to replace the bathroom soon.
