Files do no recognize a Lets Encrypt SSH certificate

Asked by Andre Metelo on 2020-06-28

I tried to find any references for this question, but I could not find anything close to the issue.

I have a WebDAV server using a Letsencrypt certificate. When I access it through any browser (Chrome, Firefox), the certificate is valid an all goes well. It also works from the default Mac OS file browser. Windows is a no go, as it never worked from the get-go due to a "feature" on its WebDAV client, and a non-issue for us.

However, when I try to use the default Files app from Ubuntu 16.04, 18.04, and 20.04 to connect to that server through the +Other Locations option (Dave://domain.com/share), it says the certificate authority is not known.

Is this done on purpose (I mean not including the Letencrypt CA by default) Or just a mishappening somewhere?

Thanks,

Does your server send Let’s Encrypt Authority X3 intermediate certificate also?

thanks Kai.

Sorry for posting on the wrong place.

IT seems that certbot is not configuring the site properly. As soon as I put the full chain line form the link it started working.

Again, thanks and sorry for posting in the wrong place.
