Sorry I'm not sure what you mean?

Between the clients and the python code I use some "basic auth" (and IP
restrictions on the reverse proxy). But I can't see how it would cause
the problem.

Between the python code and postgresql, the relevant pg_hba.conf line
is
host api api 10.10.10.43/32 scram-sha-256
Since except these two times it always works, why would it fail
then?
