Hello,

I'm a mac user. As a java developer I use intellij and copilot works fine. I'm not sure is it bug but i cant use copilot chat. In VsCode I can use copilot chat using win-ca extension as workaround but there are none for intellij. I tried using mac-ca but it doesnt work.

Added custom CA certs and added .zshrc NODE_EXTRA_CA_CERTS path but still didnt worked.

IntelliJ options -> Server Certificates -> Accept non-trusted certificates automatically is enabeled

and my log file output is;

I am having the same problem using on windows

the issue is with your node.
you can just reinstall or update it.

still if its not resolved then here is then fix (Not Reconmeded in Production environments)
export NODE_TLS_REJECT_UNAUTHORIZED=0

Installing node or updating it didn't worked. I dockerized my app and added a custom cert and it resolved the issue.
