oss certificate upload recently started failing

I have manually uploaded sucessfuly my letsencrypt cert for over a year every 3 or so months.  Today my upload failed with an error that isn't too helpful.
Error says 500:CREATE.CERT.ERROR.NameRepeatException


Does anyone know what to do in this case?

Hi, Maki.

Let’s Encrypt client wants to be run as root. Please:
1. Use sudo when ran as a normal user.
2. Check the permissions on /etc/letsencrypt. It’s probably root.

Thank you.
