Unable to connect to puppetdb with 6.0.0 docker image

Describe the bug

Hi,

I'm unable to connect to pupppetDB (using https) with 6.0.0 docker image
if I rollback to docker image 5.4.0, no problem with the exact same environment variables

I dumped network on the puppetdb server itself, and it seems the puppetboard app stop the TCP connection on his own (the container send a TCP FIN just after the ACK and do not attempt any SSL/TLS handshake)

With 5.4.0, I can see the TLS handshake juste after the TCP ACK

In the container stdout, i got :

ERROR:pypuppetdb.api.base:Could not reach PuppetDB on my.puppetdb.server:8081 over HTTPS.
ERROR:puppetboard.utils:('Connection aborted.', PermissionError(13, 'Permission denied'))

Puppetboard version

6.0.0

puppetdb 8.8.1

Environment and installation method

Docker image running on a nomad cluster
