gh pr create fails: none of the git remotes correspond to GH_HOST

[dnyw4l3n13]

Problem

gh pr create fails when GH_HOST is set to a proxy host but the git remote uses github.com.

Command

gh pr create --draft --title "..." --head feature/145-packages-interfaces-tests --base main --body "..."

Error

none of the git remotes configured for this repository correspond to the GH_HOST environment variable. Try adding a matching remote or unsetting the variable

Context

• Repository: credfeto/credfeto-dotnet-repo-tools
• Git remote: git@github.com:credfeto/credfeto-dotnet-repo-tools.git
• GH_HOST: github-api.markridgwell.com

The gh CLI refuses to create the PR because the git remote uses github.com but GH_HOST is the proxy. Other gh commands (gh issue view, gh issue edit, gh issue comment) work correctly when --repo is specified.

is this a bug in the github cli or a bug in the proxy?
