Python SDK V1 errors

I’m still using the Python SDK V1 just to little tests and I get this errors:

  File "/home/pi/.local/lib/python3.7/site-packages/algosdk/algod.py", line 231, in suggested_params
    return self.algod_request("GET", req, **kwargs)
  File "/home/pi/.local/lib/python3.7/site-packages/algosdk/algod.py", line 70, in algod_request
    resp = urlopen(req)
  File "/usr/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/usr/lib/python3.7/urllib/request.py", line 525, in open
    response = self._open(req, data)
  File "/usr/lib/python3.7/urllib/request.py", line 543, in _open
    '_open', req)
  File "/usr/lib/python3.7/urllib/request.py", line 503, in _call_chain
    result = func(*args)
  File "/usr/lib/python3.7/urllib/request.py", line 1345, in http_open
    return self.do_open(http.client.HTTPConnection, req)
  File "/usr/lib/python3.7/urllib/request.py", line 1319, in do_open
    raise URLError(err)
urllib.error.URLError: <urlopen error [Errno 111] Connection refused>

Is this beacuse the deprecated Python SDK V1 has been already dismessed or something else?

Where are you trying to connect? The above appears to be the main error which may come from a mismatched URL or port.

I’m getting the same error trying to connect to MainNet with the PureStake API. I tried using both links:

https://mainnet-algorand.api.purestake.io/idx2

and

https://mainnet-algorand.api.purestake.io/ps2

But neither worked.

I tried updating my Python certificates, but I had no luck.

open /Applications/Python\ 3.7/Install\ Certificates.command

I am continuing to get the same url open error.

This is the complete error I am getting.

I tried updating my Python-SDK download.

pip3 install py-algorand-sdk

I am still not sure where the problem is coming from. Any advice or suggestions would be greatly appreciated - thanks!

Give this a shot - api-examples/indexer_example.py at master · PureStake/api-examples · GitHub -

Thanks for the reply. I have no problem connecting to TestNet, I can do that from my node. The problem I am having is connecting to MainNet. I am unable to connect to MainNet from my node because I consistently get URL errors. I tried using PureStake as an alternative, but I got the same errors.

To update the SDK, you need to add the flag --upgrade:

python3 -m pip install py-algorand-sdk --upgrade

The follow code works for me without issue:

import json

from algosdk.v2client import algod

# Setup HTTP client w/guest key provided by PureStake
algod_address = 'https://mainnet-algorand.api.purestake.io/ps2'
algod_token = ""
headers = {
    "X-API-Key": "B3SU4KcVKi94Jap2VXkK83xx38bsv95K5UZm2lab",
}

algodclient = algod.AlgodClient(algod_token, algod_address, headers)

# get suggested parameters from Algod
params = algodclient.suggested_params()

print(json.dumps(vars(params), indent=2, sort_keys=True))

Thanks @fabrice! You are a great one! I just updated the SDK successfully. I will retry connecting to the MainNet and will edit this reply with my results.

This solved the problem. Thank you!
