Win-acme cannot renew cert

Help
1

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 2.1.2.641 (RELEASE, PLUGGABLE)
[INFO] IIS version 7.5
[INFO] Running with administrator credentials

[INFO] Please report issues at https://github.com/PKISharp/win-acme
[EROR] Unable to read renewal Jpi86wDGkkKmoiQrl5c8Tg.renewal.json: result is empty
[WARN] No scheduled renewals found.

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

IIS 7.5 doesn't support SNI.
Is there only one site?
Have you added any new sites since you got the cert?

3

yes, just one site being served on the machine. no new sites added.

Try placing a test text file (with no extension) in the expected challenge location.
And try accessing it from the Internet:
http://your.domain/.well-known/acme-challenge/test-file-name

And also update to the latest version of wacs.

i downloaded the latest wacs, are there instructions for updating wacs?

6

https://www.win-acme.com/
Latest version seems to be 2.1.8.838
Yours is 2.1.2.641

7

yes, i have the latest. is there a procedure for upgrading? can’t seem to find anything information on this.

This is all I could find:

thanks, looks like it’s just a straight copy over. so the new version reports pretty much the same error:
