Max retries exceeded with url: | SSLError: HTTPSConnectionPool

grthilak

Hi,
I am getting the below error quite frequently. Last time when i got it, tries were like not more than 4 to 5 times. Kindly help.

SSLError: HTTPSConnectionPool(host='api.kite.trade', port=443): Max retries exceeded with url: /instruments/NFO/BANKNIFTY18MAYFUT?api_key=XXX&access_token=XXX(Caused by SSLError(SSLError("bad handshake: SysCallError(-1, 'Unexpected EOF')",),))

sujith

Can you provide the exact error message and status code from the API?

Hi sujith,
I am also getting same issue .can you provide a way to resolve the issue. while executing second line

kite = KiteConnect(api_key="xxxxxxx")
data = kite.generate_session("xxxxxxxxxxxx", api_secret="xxxxxxxxxxxxxxxxx")

sujith

You can refer to the similar thread here.

hi,

I am getting the same error today;

"
HTTPSConnectionPool(host='api.kite.trade', port=443): Max retries exceeded with url: /session/token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1076)'))) "

i am using python API -
kite = KiteConnect(api_key=key_secret[0])
data = kite.generate_session(request_token, api_secret=key_secret[1])

how to resolve?

sujith

You seem to be using a self-signed SSL certificate, you need to get the certificate from a recognized authority.
