Start with test/http2-abort.js around lines 110-113 and run the failing Concurrent aborts (2nd variant) test. Investigate why its secure-server setup intermittently produces the reported OpenSSL ASN.1 illegal-padding error, using the linked CI run for context. Done means the test runs reliably without this failure.
