Failed to verify TLS certificate with Telegraf

It seems to be solved. Inspired by:

How to skip tls verification when getting config file over https

Hi, I do not believe we have an ignore or disable TLS or cert verification for remote config files. I think there is good reason to not allow this given the sensitive nature of them at times. However, if you have the cert, then I would suggest adding it to your system cert pool and I believe Telegraf will look there for it.

I took the SSL certificates using:

openssl s_client -connect 172.16.20.11:8006

Then copy it on a file located at /usr/local/share/ca-certificates/local_proxmo.crt.
Running the commands:

update-ca-certificates
update-ca-certificates --fresh

This basically add the Proxmox certificate as a trusted cert on the machine which host Telegraf.

Now I have a E! [inputs.proxmox] Error in plugin: unexpected end of JSON input error, but at least the SSL/TLS error is fixed !
