"Connection to rekor.sigstore.dev timed out" #377
Description
During a matrix build, one package (openapi-mcp-server) has failed twice while others have passed successfully by integrating the attestations with nothing I can think of that would be different (it is however failed twice sequentially to the /api/v1/log/entries/):
