Can you please let me know what file I need to remove to fix this issue?

here is the fix

1) Find where root certificates have been stored in your Qnap, mine was in /etc/ssl/certs

cd /etc/ssl/certs
ls -lth | grep DST_Root_CA_X3.pem
rm -f 2e5ac(whatever your symlink is)
rm -f DST_Root_CA_X3.pem

2) Copy these two files in /etc/ssl/certs

https://letsencrypt.org/certs/isrgrootx1.pem
https://letsencrypt.org/certs/lets-encrypt-r3.pem

3) reboot your qnap.
