Cannot download bundle at http://repo1.maven.org/maven2/....oss-catalog-1.6.jar: HTTP Server 'Not Implemented'

Question

Recently, I re-imaged our machines from Windows 7 to Windows 10. Ever since then, on opening Eclipse, I've been unable to open the M2E Catalog. This means I can't install Maven's the Tycho Project Configurator. As this is an organization, it's pretty certain there may be proxy servers. However, I've not been able to obtain its details. Essentially, installing the Tycho Project Configurator is what I'm trying to do.

Steps to reproduce:

Eclipse Oxygen -> Quick Access -> "m2e"

Error on Eclipse GUI: "Discovery completed without finding any extensions. Please check your network connection and try again".

Eclipse logs:

Java version: 1.8.0_181

Any suggestions?

Try a newer release of Eclipse. Maven Central only provides downloads by https, now.
