Non-recoverable failure in name resolution

[the86hitman]

Hi everyone,

Trying to use network functions, but when I try to use the data connection, Python throws me this error:

gaierror: (4, 'Non-recoverable failure in name resolution')

this happens if I try to run, for example:

s=imaplib.IMAP4_SSL('imap.gmail.com')
OR
urllib.urlopen('http://www.bbc.co.uk')

anybody know what the above error means? If I use wlan instead on my mobile, there is no error.
I signed python shell with full capabilities.

hello the86hitman

if its working on the wlan then may be the problem with your service provider. why don't you check after some time.

thank you for your suggestion, but no the network is fine. I am able to browse the internet without any problems using S60 browser with data connection.
It just seems that Python shell refuses to connect via data connection.

>>> import imaplib
>>> s=imaplib.IMAP4_SSL('imap.gmail.com')
Traceback (most recent call last):

I did not find any issue in executing the code. Which PyS60 version did you try with and on which device ?
I tried with PyS60 1.9.6 on E71.

Also, did you install the ssl SIS available with the PyS60 installer ?

I have the same problem and there's evidence that it has nothing to do with the network operator. I use "smart connect" which sets up a dummy packet data connection. It is through this packet data connection that it will connect to wifi if available, otherwise it connects to the cellular network data. Anyway, as the86hitman said, I can connect directly through my wifi access point just fine, but if I select the dummy packet data connection (which goes to wifi anyway) I get the non-recoverable failure in name resolution. Python 1.9.7 N82 firmware 3 with SSL installed.

I've seen this error note, when my SIS was missing "NetworkServices" capability. No problems with emulator shell script, so don't know what could be the problem there...

Just a comment,

That did it -- thanks. I signed the python script shell with all capabilities including network services.
