API connection error #176

Closed ebeullard closed 2 years ago

ebeullard commented 2 years ago

after connecting without issue for about a month, I am now getting the following error: ClientConnectorCertificateError: Cannot connect to host api.devnet.solana.com:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')]

The snippet presented in github was used to test the connection but the error remains: from pythclient.pythclient import PythClient from pythclient.pythaccounts import PythPriceAccount from pythclient.utils import get_key

solana_network="devnet" async with PythClient( first_mapping_account_key=get_key(solana_network, "mapping"), program_key=get_key(solana_network, "program") if use_program else None, ) as c: await c.refresh_all_prices() products = await c.get_products() for p in products: print(p.attrs) prices = await p.getprices() for , pr in prices.items(): print( pr.price_type, pr.aggregate_price_status, pr.aggregate_price, "p/m", pr.aggregate_price_confidence_interval, )

I am running python 3.10 at the moment.

This is an SSL error -- it looks like you don't have the necessary certificates required for your computer to securely query the devnet solana host.

Closing because this is not a pyth-client problem.

fwiw you may be able to fix this using pip install --upgrade certifi

(certificate issues are always a pain though...)

Hi,

I tried the below but no success ( I was running certifi 2022.5.18 and it worked for a few weeks). Would you have any other pointer?

regards
