Pushbullet Notifications Failing (Ubuntu, v1.1.1 [33a7874])

[zacharylm]

Since the last update, SAB has started to fail when trying to send a notification via Pushbullet. Other applications (e.g. Couchpotato, Sonarr) have no issue doing the same. Below is the pertinent portion of the log. Please let me know if any other info is needed.

Looking up this message it seems to have to do something with an TLS problem.
We just use the build-in SSL provider from Python, nothing special really and nothing has changed between versions.
So I think it's something with Pushbullet's API certificate, but I can't tell you what exactly..

[sander]

As you're on Ubuntu, let's analyze your setup with this small script that does about the same as SABnzbd itself:

Code: Select all

import httplib, urllib, json

conn = httplib.HTTPSConnection('api.pushbullet.com:443')
conn.request('POST', '/v2/pushes', json.dumps({'type': 'note','device': "bla",'title': "title",'body': "msg"}),headers={'Authorization': 'Bearer ' + "dddd8d88d8d8", 'Content-type': 'application/json'})
res = conn.getresponse()

print res.status
print res.read()

Result on my Ubuntu:

Code: Select all

$ python test-pushbullet.py 
401
{"error":{"code":"invalid_access_token","type":"invalid_request","message":"Access token is missing or invalid.","cat":"(=^･ω･^)y＝"},"error_code":"invalid_access_token"}

So, a correct 401. No Ugly SSL / EOL message.

Please post back your result.

@zacharylm ... follow up please ....

Apologies for the late response, apparently I need to check my forum setting as I never received an email notifying me of a reply to my post. Anyhoo, here's the result:

[sander]

OK, good that you follow up.

The result of the python script shows your Ubuntu / python / SSL setup has a problem. The problem is not in SABnzbd; you can generate the problem with a few lines of plain python code, without any SABnzbd involved.

Googling "ssl.SSLError: [Errno 8] _ssl.c:510: EOF occurred in violation of protocol" does not immediately make clear what is going on ... It could be related to SSL 2/3: python tries that first, but api.pushbullet.com does only support TLS 1 and higher (which is a good thing)

Which Ubuntu are you running? Fully updated?

[zacharylm]

Running 14.04.5 LTS (GNU/Linux 4.4.0-53-generic x86_64). As far as apt is telling me, and save for doing the release upgrade to 16.04, I'm up-to-date.

I tried on my Ubuntu 14.04.5 (instead of my 16.04 as I did before) and ... ouch:

Same problem :-(

Even with this 3-liner I get the error on my Ubuntu 14.04.5 with api.pushbullet.com (not with other HTTPS sites):

Code: Select all

import urllib2
response = urllib2.urlopen('https://api.pushbullet.com/')
html = response.read()

Result:

    raise URLError(err)

[zacharylm]

Hmmm. Well, I'm glad that it can be reproduced, but it sucks for the big picture. Also interesting that SABnzbd is the only program on my box that seems to be affected. Went back and was still able to do test notifications from Sonarr and CouchPotato (can't seem to find a way to test Headphones, though) so I wonder what is different in their implementations.

[sander]

It seems to be related to the version of Python:


Python 2.7.11 on Ubuntu 14.04.5 is OK:

Code: Select all

sander@haring:~/pushbullet-test$ /opt/python2711/bin/python urllib2-2.py
{"cat":"(=^.^=)","happy_to_see_you":true,"message":"Welcome to the Pushbullet API!"}

Python 2.7.6 on Ubuntu 14.04.5 is not OK:

Code: Select all

sander@haring:~/pushbullet-test$ python urllib2-2.py
Traceback (most recent call last):
  File "urllib2-2.py", line 2, in <module>

The same error as you got;

Code: Select all

[Errno 8] _ssl.c:510: EOF occurred in violation of protocol>

[sander]

Hmmm. Well, I'm glad that it can be reproduced, but it sucks for the big picture. Also interesting that SABnzbd is the only program on my box that seems to be affected. Went back and was still able to do test notifications from Sonarr and CouchPotato (can't seem to find a way to test Headphones, though) so I wonder what is different in their implementations.

And Sonarr and CouchPotato run on the same Ubuntu 14.04, with the same Python?

I checked CouchPotato, and it uses the same url

Code: Select all

 url = 'https://api.pushbullet.com/v2/%s'

so there is no difference there. :-(

[zacharylm]

As far as I can tell, yeah. I double-checked the init scripts in /defaults/etc and I don't seem to be calling out a different version of Python. Is there a better way to be sure?

[sander]

Too bad: I tried plain HTTP as a workaround, but:

Code: Select all

2016-12-12 15:19:44,098::INFO::[api:797] Sending Pushbullet notification
2016-12-12 15:19:45,848::ERROR::[notifier:485] Bad response from Pushbullet (403): {"error":{"code":"invalid_request","type":"invalid_request","message":"This server is only accessible over HTTPS.","cat":"(=^â¥^=)"},"error_code":"invalid_request"}

... so alas HTTP is not a workaround.

EDIT:

I looked around, but I don't know how to solve this. So, workaround is to install Python 2.7.9 or higher on a Ubuntu 14.04, and use that.

[sander]

Good news: I got it working on my Ubuntu 14.04, both standalone and in SAB.

Standalone ... please fill out your pushbullet apikey and then test:

Code: Select all

import requests, json
device = "bla"
title = "my title"
msg = "my message"
apikey = "o.kdLtzjXCMzblblabla"   # Fill this out!!
if True:
        data_send = {"type": "note", "device": device, "title": title, "body": msg}
        res = requests.post('https://api.pushbullet.com/v2/pushes', data=json.dumps(data_send),
                headers={'Authorization': 'Bearer ' + apikey, 'Content-Type': 'application/json'})
        print res.status_code

If that works, I have a solution for SAB on with python 2.7.6.
