No experience with this error for Postgres specifically, but in terms of networking it means that there is a server somewhere between the host and the CA (certificate authority) which is self-signing instead of deferring to the CA.

There’s probably a setting in Postgres to allow that.

Otherwise, it would need to be rectified in the network chain.

You might be able to use traceroute -v to identify the source of the issue.
