Shower drain pipe (riser) not plumb

[Kaymandavis]

I have an Oatey brass 'no caulk' shower drain. It uses a rubber gasket that sits over the PVC drain pipe (riser, correct?). The riser is enough out of plumb that the rubber gasket doesn't seal properly. I did a leak test and it failed.
Before opening up the basement ceiling and cutting pipes to get things plumb, can i just replace the rubber gasket with silicone? I figure if it works, is works. If not, I'm no worse off for trying and can always resort to opening the ceiling below to fix the issue.
Because the basement ceiling is only partially finished, I have a line of visibility that will allows me to see if there are leaks before the drywall would bow and collapse.
My plumber did the rough-in plumbing to get the p-trap in place, but I'm guessing it wasn't level. So when I put in the riser it was not plumb. Should he have to fix it or me for having glued in the riser?
If the silicone will work, that would be easiest. Maybe not best practices, but will it work?
Thanks

Take the rubber compression sleeve out. Slather in dope. Dope the threads of the slotted compression nut and re tighten.

Are you using that flat tool to tighten it?

I have a similar issue with my 2" riser out of plumb. I need to move it 9" to install a shower no hub linear drain but am concerned with leaks. Is this issue common? Easily fixed?

Did the recommended solution fix your issue?

You're trying to tweak a pipe 9"?

Your trying to tweak a pipe 9"?

I'm moving the 2" shower riser 9" to install a linear drain for a shower rather than a bathtub. I was planning to use 2 90's for the move, but not sure if my no hub linear drain will leak. If I remove more concrete and the p trap I can redo the original work but that is a lot of work. Hoping for a better solution.

Sorry if I hijacked this thread. Just seemed like the same issue.

Thanks
