In-line chlorinator leaking

[miscad]

Hello,
I have a Hayward, CL200 in-line chlorinator. Ever since I opene dthe pool a few weeks ago, it has a slight leak. Lid is secure, plug is secure - any ideas what other components/ parts might be leaking? It almost seems like it is coming from underneath the unit? PVC connections seem ok as well. I've added some pics for reference.
TIA!

If you don't see it leaking at any of the union fittings or anywhere obvious, you may need to remove it and inspect the bottom. I wonder if it froze and cracked over the winter from trapped moisture.
