### Retrying After Temporary Errors
Some errors happen due to network connection issues, high load, or other rare situations.
If it looks like a failure might be temporary, try re-running all the jobs on the PR using one of these methods:
1. `@mergifyio update`
2. `@dependabot recreate` (for dependabot PRs only)
3. click on the failed job, and select "re-run all jobs". If the workflow hasn't finished, you might need to cancel it, and wait for it to finish.
Here are some of the rare and temporary errors that should be retried:
- Docker: "buildx failed with ... cannot reuse body, request must be retried"
- Failure in `local_listener_fixed_port_localhost_addr_v4` Rust test, mention [ticket #4999](https://github.com/ZcashFoundation/zebra/issues/4999) on the PR
- any network connection or download failures
We track some rare errors using tickets, so we know if they are becoming more common and we need to fix them.
