2653777 - Phyton connection to HANA database using hdbuserstore-key fails

Accordingly to Connect Method and Python Connection Properties, it is possible to use a userkey for an SAP HANA database connection with python:

"Connect by using the database parameters stored in hdbuserstore:
connect(key=<hdbuserstore-key>)"

but it is not possible to establish a connection with dbapi.connect and the usage of a valid hdbuserstore key.

Error:
sapadm@*******:/usr/sap/SAP/SYS/global/hdb/custom/scripts> python saptest.py
Traceback (most recent call last):
File "saptest.py", line 7, in <module>
connection = dbapi.connect(userkey='SAPUSERTESTSYSTEMDB')
File "/usr/sap/SAP/HDB00/exe/python_support/hdbcli/dbapi.py", line 85, in __init__
self.__connection = pyhdbcli.connect("%s:%d" % (address, port), 'HDB', user, password, self.__properties)
hdbcli.dbapi.Error: (-10709, 'Connect failed (no reachable host left)')

hdbuserstore list:

DATA FILE : /usr/sap/SAP/home/.hdb/sap123456/SSFS_HDB.DAT
KEY FILE : /usr/sap/SAP/home/.hdb/sap123456/SSFS_HDB.KEY
KEY SAPUSERTESTSYSTEMDB
ENV : localhost:39013

The connection with hdbsql and this userkey is possible without any problem.
