The Git for Windows CI web app sometimes returns HTTP errors of "502 bad gateway" or "503 service unavailable" [1]. Wait a little and retry the request if this happens. [1] https://docs.microsoft.com/en-in/azure/app-service-web/app-service-web-troubleshoot-http-502-http-503 Signed-off-by: Lars Schneider <larsxschneider@xxxxxxxxx> --- Hi, this should make the Git for Windows build a bit more stable. We saw a few 502's recently. E.g. https://travis-ci.org/git/git/jobs/226669324 I did not add any checks to avoid an endless loop because TravisCI would shutdown the worker if there is no output for more than 10min. Therefore I think we don't need to handle this case ourselves.
