--- Comment #11 from Mark Thomas <ma...@apache.org> --- Thanks for the additional information. I can now reproduce this (thanks to Microsoft for the free azure credits). I have two clean Tomcat 9.0.x builds. One locally, one on Azure. Key config is HTTPS / OpenSSL / NIO2. Locally the upload works. Uploading to Azure fails. Switching the Azure instance to NIO makes the problem go away. I'm starting to investigate now. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
