Hi @lance6716. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.

this PR might backport to master branch later, maybe just add http2: client connection lost

as we will pause when meet un retryable error, it should be fine for our test
