complains about certificate

[AdamRGrey]

Describe the bug my SSL certificate is valid, i promise. But when I try to access my server, every time, I have to tell it to accept the certificate. (today is 2024-01-30, notably within the timeframe)

Environment

• cadaver 0.23.3
• neon 0.31.2: Library build, IPv6, libxml 2.9.10, zlib 1.2.11, GNU TLS 3.6.14.
• readline 8.1
• OS: Debian 11
• SSL library version:OpenSSL 1.1.1w-0+deb11u1 amd64

To Reproduce

1. have a server with a let's encrypt certificate
2. have nextcloud on it
3. cadaver -t https://[DOMAIN]/nextcloud/remote.php/dav/files/[USER]/

output:

WARNING: Untrusted server certificate presented for `[DOMAIN]':
Issued to: [DOMAIN]
Issued by: Let's Encrypt, US
Certificate is valid from Mon, 01 Jan 2024 01:01:28 GMT to Sun, 31 Mar 2024 01:01:27 GMT
Do you wish to accept the certificate? 

Debugging output have to do this after connection, right?

note also neither curl nor wget complain, so I'm quite confident my system should trust the certificate

Did you build the binaries from source, if so how did you build them? neon has to be configured to use the correct system CA if you build with GnuTLS and neon 0.31.
