Since last week, I've been having the same connection issue with Datastream via python. I use the following:
from pydatastream import Datastream
DWE = Datastream(username="DS:XXXXXX", password="XXXXXXXX")
But when I attempt to connect, I receive the following connection error:
WebFault: b"Server raised fault: 'User 'DS:XXXXXX' logon failed: Delegate Source 'DSPermissionsPassword' reports: No response from source DSPermissionsPassword'"
I've reached the library's developers here: https://github.com/vfilimonov/pydatastream/issues/21
It was working just fine 2 weeks ago, but it stopped out of the blue. Does anyone know what the problem might be?
