Proxmox cluster notification error SSL

[tduf]

Hi all,

I'm trying to use Discord for my cluster (2 nodes + 1 quorum / v8.4.1) notifications with Discord.
When I push the "test" button to test the connection, this message occurs :

"Could not test target: https://discord.com/api/webhooks/<masked>: Connection Failed: native_tls connect failed: error:0A000086:SSL routines:tls_post_process_server_certificate:certificate verify failed:../ssl/statem/statem_clnt.c:1889: (hostname mismatch) (500)"

No problem with the same configuration into my Proxmox backup server...

Any help ?

Thks in advance.

I too am having the exact same issue. It was working without fail for several weeks. Cert is valid and installed on all nodes. Same cert is used on the target URI. Cert is from Let's Encrypt.

Here is how I solved this:
I converted the PEM containing the intermediate cert to .crt:

openssl x509 -inform PEM -in chain.pem -out chain.crt

I then copied the cert to this location:

cp chain.crt /usr/local/share/ca-certificates

I then updated the certs:

update-ca-certificates

I then validated my URL:

curl --verbose https://my.secret.ssl.site.com
