Weird ... but I'm afraid you have come to the wrong place for help.
This mailing list deals with PG server bugs, and the server seems to
be the one component that is clearly not at fault in your case.
It could be PGBouncer's fault, so I'd suggest inquiring through their
support contact. (I do not know offhand what that is, but it's not
here.) But TBH, if reinstalling the identical certificates on the
client machine makes the problem go away, it's hard to conclude that
it's not a client-side bug.
