Hi
Weird. According to
http://geopy.readthedocs.org/en/latest/#geopy.exc.GeocoderServiceError this
is the most generic exception, only used when there is not a more specific
one (which include by the way problems caused by connectivity and
authorization). The message of the exception is supposed to be the one
delivered by the original application. In this case: "Nombre o servicio
desconocido":
I am wondering if there is an error message matching the one you receive in
PostgreSQL.

Somehow I expected that answer. I am not a python expert, but it happens
that different pieces of code at the end do not use the same libraries or
framework code by configuration. But if you are positive on that, no more
discussion.

Well, if it worked a few times and then never again, then something must
have changed in your system. This could also be a possible reason for the
error.
Sorry for asking obvious things, but it happened to me to oversee some of
them in the past: Are you making the calls from the same computer?

So it looks like a timeout problem with a confusing error message.
A possible way to follow this up would be to call another webservice from a
python function in PG and see if it behaves the same.
Another way to analyze the problem could be to sniff the network traffic and
see what really happens when you make the function call. This could help at
least to discard network problems and may lead to some useful information.
I hope that you will find a solution.
