If you insulate the pipes, the condensed water does not fall from the pipes.
Check if there are any insulation cracks on the bent pipe.

thicker insulation.

Install the insulation not to be get wider and use adhesive on the connection part of it to prevent moisture
entering.
CAUTION
Bind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. (When binding the pipe with
finishing tape, be careful not to reduce the thickness of the insulation.)
Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe.
When the thickness of insulation is reduced, supplement the reduced thickness with additional insulation.
