Python redis library not working unlike command line

Question

I have a remote Linux Redis 7.0 server which I reach through a spiped tunnel.

Launch spiped locally:

spiped -F -e -s 127.0.0.1:6379 -t REMOTESERVER:6379 -k /etc/spiped/redis.key

and as expected I can connect to the remote Redis server via the command line utility:

(redis_test) bob@Roberts-Mac-mini redis_test % redis-cli      
127.0.0.1:6379> AUTH myverysecretpassphrase
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> keys *
1) "test"
127.0.0.1:6379> exit

So all as expected. So tried the very simple python program:

import redis

r = redis.Redis(host='MYSERVERIP', port=6379, password='myverysecretpassphrase')

r.set('foo', 'bar')
value = r.get('foo')
print(value)

but get a long error trace:

(redis_test) bob@Roberts-Mac-mini redis_test % python test1.py 
Traceback (most recent call last):

Here is my environment:

Just to exclude typos, are you actually replacing MYSERVERIP with 127.0.0.1? If not, that may be the cause of the issue - as the remote Redis server would be tunneled through 127.0.0.1:6379, according to your spiped command line.

So that should read instead:

r = redis.Redis(host='127.0.0.1', port=6379, password='myverysecretpassphrase')
