Hey
@loud-kite-94877. By a chance, we also encountered some issue connecting to our mysql cluster caused by this bug and took our day to find out the cause of the issue.
I prepared two very smalls for fixing that issue and mentioning the port value on the docs of the helm values.
It would be great if you also take a look:
