FileZilla Forums

I'm able to view that acme website mentioned in the log file via browser with no problems. It shows there is a valid cert on the acme endpoint. Unsure why FileZilla is saying Certificate is Trusted: No.

I was able to download certbot and provision a certificate via their tool, so it seems like the issue is with FileZilla.

Which version of FileZilla Server are you using? Are you by chance using a firewall or other snake-oil product that performs TLS inspection?

I'm using server version 1.6.7 just downloaded it a few hours ago this is a new setup. Windows firewall is turned off for testing trying to get this to work.

Cannot reproduce, works over here just fine.

If from the server's machine you try to connect to https://acme-v02.api.letsencrypt.org/ with a browser, what does it say about the certificate?

Going on a hunch here: Outdated Windows system trust store?

The certificate is valid via browser as mentioned in the first post.

It's a brand new install of server 2019, latest updates. It works fine using https://certbot.eff.org/

No idea why it doesn't work inside filezilla. I'll just use certbot and have it restart the service post-deploy.

Your web browser uses its own trust store. You need to use at your operating system's trust store.

Please check whether your operating system's trust store is up-to-date, containing the trust anchors for the Let's Encrypt certificates and remove any expired certificates.
