Error: sh][ERROR] wget exited with exit code 4
Error: Process completed with exit code 1.

It is enough to make an empty commit "retry CI" and push it to re-run the Github CI.
It happened for me twice:
https://github.com/openjdk/jdk21u-dev/pull/1663#event-18416642257
-> (I did not save the log, unaware how to access it now)
https://github.com/openjdk/jdk21u-dev/pull/1664#commits-pushed-c00e2ab
-> https://github.com/jankratochvil/jdk21u-dev/actions/runs/16026488095/job/45215623689
