Could you provide details on how the nrfutil toolchain-manager makes its internet requests? Or even better, how to add certificates to be trusted in making its TLS connections?
Our corporate internet security systems are causing the connections to fail, and we need to know what framework is used by the toolchain-manager so that we can work with our IT to resolve or workaround it. Here are some examples of such workarounds for other development tools (Python PIP, NPM, etc.): https://help.zscaler.com/zia/adding-custom-certificate-application-specific-trust-store
For context the nrfutil toolchain-manager gives us this error:
C:\>nrfutil toolchain-manager searchError: Failed to retrieve toolchain-index
Caused by: 0: Failed to download index 1: Get request failed 2: developer.nordicsemi.com/.../index-windows-x86_64.json: Connection Failed: tls connection init failed: invalid peer certificate: UnknownIssuer 3: invalid peer certificate: UnknownIssuer
Or a similar error via the nRF Connect VS Code extension, in that case "Failed to fetch available toolchains." is the high-level error that pops up, but the accompanying console output shows same error as nrfutil toolchain-manager gives on command-line.
I have seen other DevZone posts (such as "Failed to fetch available toolchains." on Visual Studio Code ) with same error, but none of them explain how to add trusted certificates so the download works on a network employing SSL/TLS inspection.
Again this is not an issue with the nrfutil toolchain-manager or nRF Connect VS Code extension itself. But do need to know more about how it works to enable us to get it to work as intended in our corporate environment.
