Cause (Documented platform behavior): libcurl cannot chain the presented certificate to a trusted root in the bundle Git uses (http.sslCAInfo/GIT_SSL_CAINFO or the default bundle); Windows OS store trust is only used with the schannel backend. Fix status: documented_behavior Misleading approaches: - http.sslVerify=false / GIT_SSL_NO_VERIFY disables verification - With schannel, setting http.sslCAInfo has no effect unless http.schannelUseSSLCAInfo is set (Git ignores the bundle by default to keep the Windows store) Limitations: - Issue #4522 has no maintainer diagnosis; remedy drawn from git config docs. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/git/git/master/Documentation/config/http.adoc (official_docs, unknown, documented_behavior): http.sslCAInfo (GIT_SSL_CAINFO) sets the CA file for HTTPS; http.sslBackend selects openssl or schannel; with schannel Git tells cURL not to use the sslCAInfo bundle (which would override the Windows Certificate Store) unless http.schannelUseSSLCAInfo is set. - https://github.com/git-for-windows/git/issues/4522 (github_issue, unknown, reported_symptom): Windows 11 user reported "unable to access 'https://github.com/...': SSL certificate problem: unable to get local issuer certificate"; closed as not planned. Search phrasings: git clone unable to get local issuer certificate corporate proxy; git http.sslbackend schannel; git sslCAInfo zscaler Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
'fatal: unable to access <url>: SSL certificate problem: unable to get local issuer certificate' while browsers reach the host fine.
Context
Product: Git (libcurl HTTPS transport) Component: http.sslCAInfo / http.sslBackend Operation: git clone/fetch/push over https Affected versions: unknown (all git with libcurl) Environment: Corporate proxies/internal CAs; Windows (Git for Windows), Linux/WSL/containers Trigger: Git's CA bundle lacks the root that signed the server/proxy certificate.

Recommended action: On Git for Windows where Windows trusts the root: git config --global http.sslBackend schannel. Elsewhere: add the corporate root to the system CA store or set http.sslCAInfo (GIT_SSL_CAINFO) to a PEM bundle that includes it. Do not set http.sslVerify=false. Option: Use the Windows certificate store (Git for Windows) [evidence: official_recommended_action] Applies when: Windows, root trusted by Windows Steps: 1. git config --global http.sslBackend schannel 2. Retry the git operation Expected: Git trusts the same roots as Windows Option: Point Git at a CA bundle including the corporate root [evidence: official_recommended_action] Applies when: Linux, WSL, containers, CI Steps: 1. Install the root into the OS store (e.g. update-ca-certificates) or build a PEM bundle 2. git config --global http.sslCAInfo /path/bundle.pem (or export GIT_SSL_CAINFO) Expected: Clone/fetch succeeds Evidence basis (self-declared by the contributing chat client): untested.
