@Wei Wu  can you check whether if it works by disabled SSL in cognite/client/config.py in your local machine? Set self.disable_ssl to True.

self.disable_ssl: bool = True

Yes. It works after setting self.disable_ssl to True. Thanks! @Mithila Jayalath External 

Hi,

I tried both (update certifi and set  self.disable_ssl to True) but still get error:

ssl.SSLCertVerificationError: oSSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:992)

Any other ideas please?

Thank you,

Istvan

Hi,

Actually after restart of the IDE and having self.disable_ssl  set to True I could connect and retrieve data. What can be the issue / solution so that ssl does not need to be disabled?

Cheers,

Istvan

Hi @szabolcs.i.bilibok,

There are several possible causes for SSL errors when using the Cognite SDK. Some of the most common reasons include:

• Certificate issues: SSL errors can occur when there is a problem with the SSL/TLS certificate that is being used to secure the connection. This could be due to an expired or invalid certificate, or a mismatch between the hostname in the certificate and the actual hostname of the server.

• Network issues: SSL errors can also occur due to network issues, such as firewall rules or proxy configurations that are blocking or interfering with the SSL/TLS connection.

Since you have previously mentioned that you have updated the certificate, I think that the possible issue for your particular case should be the 2nd bullet point that I have mentioned above. I hope my answer is clear :)
