We're starting to roll out our new Devpi installation to projects now that we've tested it extensively. We have one master and three mirrors. For the purposes of this email, the mirrors are load-balanced behind the domain name "devpi.example.com," and the master is available at " primary-devpi-server.example.com." We configured our Pipenv and Pip installations to use this index URL: https://devpi.example.com/org_name/stable/+simple/ That URL will use the mirrors. The "org_name/stable" index extends root/pypi and also includes our internal projects. Everything appears to be working on the client. No errors, installs are going off without a hitch. However, the Devpi server on the master machine (not the mirrors) logs a ton of errors like the following: [req78237] [Rtx14602] while handling https://primary-devpi-server.example.com/root/pypi/+simple/internal_project_... : The project internal_project_name does not exist. What is the cause of these errors? Is this something that should concern us, or something that we can ignore? "internal_project_name" installs just fine, but for some reason yields those errors on the master server. Thanks, Nick
