KNIME Analytics Platform

Dear Sir/Madam,

I have installed KNIME 4.7.2 in my machine and try to install the knime extensions, it says below error:

Some sites could not be found. See the error log for more detail.
Unable to read repository at https://update.knime.com/partner/4.7/content.xml.
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Please let me know is there any issue with site reaching/connectivity or any thing needs to be taken care.

Thanks & Regards,
Gopal

The same thing happened to me, and in the end, I reinstalled KNIME and now it works fine.

Hi,

May be let me reinstall it and check again. but assume that if still issue persists what other areas we need to check and verify…

Hi @gokarana_1977 -

Can you check this thread to see if either of the suggestions works for you?

Hi @siegerw and welcome to the forum.

Did you try either of the suggestions in the linked thread above? Sometimes changing the https:// to http:// is sufficient, but if you are on a tightly locked down corporate machine you might have to update the certificates.

(Also make sure you are not on a corporate VPN, if possible.)

Thanks for the reply and welcome. Yes did try changing to http:// and also reinstalled software. No bueno. Not on VPN but am on locked down corporate computer. Is there a thread on how to update certificates.
Thanks

The video linked in the other thread walks through the process of updating certs step by step. You might have to get help from your corporate IT though - the more locked down your machine, the more likely that is of course.

Corporate IT issue for me. Able to connect and update extensions from my home network
