i am using wacs on a windows 2008 IIS server. the installation went flawlessly and the 1st cert was received. now 3 months later the automatic renewal setup is failing with this message:
C:\wacs>wacs --renew --baseuri “https://acme-v02.api.letsencrypt.org/”
[INFO] A simple Windows ACMEv2 client (WACS)
[INFO] Software version 22.214.171.1241 (RELEASE, PLUGGABLE)

[INFO] Please report issues at https://github.com/PKISharp/win-acme
[EROR] Unable to read renewal Jpi86wDGkkKmoiQrl5c8Tg.renewal.json: result is empty

i haven’t found any help online for this issue. does anyone know how to fix this?
