acme.sh on Syology NAS renew errors... Help!

[rsirota]

I have a wildcard certificate from CloudFlare. The certificate has been installed properly and works. However my Task to renew the certificate is giving me errors. I don't know if it's too soon to do the renewal (cert expires on 7/5/26.

My task in Synology Task Manager is:
docker exec acme-sh acme.sh --log --renew -d "_myDomain_.com" user root and executes monthly.

The email I get back after it runs contains the following:
[Sun May 3 15:36:08 UTC 2026] The domain '_myDomain_.com' seems to already have an ECC cert, let's use it. [Sun May 3 15:36:08 UTC 2026] Renewing: '_myDomain_.com' [Sun May 3 15:36:08 UTC 2026] Renewing using Le_API=https://acme.zerossl.com/v2/DV90 [Sun May 3 15:36:09 UTC 2026] Using CA: https://acme.zerossl.com/v2/DV90 [Sun May 3 15:36:09 UTC 2026] No EAB credentials found for ZeroSSL, let's obtain them [Sun May 3 15:36:09 UTC 2026] acme.sh is using ZeroSSL as default CA now.

Based on the last couple of lines I thought my email was not registered so I did the following:
acme.sh --register-account -m rob@myDomain.com executed in terminal as root.

And it returns:
[Sun May 3 08:29:29 AM PDT 2026] Registering account: https://acme.zerossl.com/v2/DV90 [Sun May 3 08:29:31 AM PDT 2026] Already registered [Sun May 3 08:29:31 AM PDT 2026] ACCOUNT_THUMBPRINT='REDACTED'

However, when I run the Synology Task I still get the same messages.

I have attached the acme.sh.log (with my domain name changed)

I hope some can help... Did I miss a setting? Do you need more info... Ping me if necessary...
