How to Fix GitHub Copilot Certificate Errors (UNABLE_TO_VERIFY_LEAF_SIGNATURE)

We explain the solution when GitHub Copilot becomes unusable due to certificate errors like 'unable to verify the first certificate'. We introduce specific steps involving changing ESET settings.

How to fix the following error in GitHub Copilot

GitHub Copilot stopped working around April 19, 2024. The error message is as follows:

[ERROR] [ghostText] [2024-04-21T04:06:46.900Z] Error on ghost text request: (FetchError) unable to verify the first certificate [ERROR] [certificates] [2024-04-21T04:06:46.901Z] Your current Copilot license doesn't support proxy connections with custom certificates. Please visit https://gh.io/copilot-network-errors to learn more. Original cause: {"type":"system","_name":"FetchError","code":"UNABLE_TO_VERIFY_LEAF_SIGNATURE"}

Solution

This seems to be a bug in ESET. Turn off “Enable SSL/TLS” in ESET’s Advanced setup. img_1.png
