My rtpengine.conf

[rtpengine]
table = 0
interface = int/10.41.0.19;ext/172.16.42.20!xxx.xxx.xxx.xxx
listen-ng = 10.41.0.19:12221
listen-http = 10.41.0.19:8000
timeout = 60
silent-timeout = 3600
tos = 184
port-min = 50000
port-max = 51000
enable-jb = true

I'm using the URL of the listen-http for the connexion.

Thanks for your reply!
When I do request to the localhost (I ran this script on rtpengine instance):

        async with session.post('http://localhost:9999/ng', data=data) as response:
            result = await response.text()
            result = result.split(" ", 1)
            print(result)
            print(type(result))
            print(result[1])
            print(type(result[1]))
            r = bencodepy.decode(result[1])
            print(r)

at line 17, I got this
print(result):
['0_5679_1',__ 'd5:callsl36:d38851c7-cf98-4cf8-9e6f-d0ab13877a7ee6:result2:oke']
print(type(result)):
<class 'list'>
print(result[1]):
d5:callsl36:d38851c7-cf98-4cf8-9e6f-d0ab13877a7ee6:result2:oke
print(type(result[1])):
<class 'str'>

and then that error that was posted above at the command bencodepy.decode(result[1])

I hope it could be useful for someone who will use your script.
