Https://plugins.gradle.org/m2/ not accessible?

Does anyone have an idea, why I might be getting a page not found?

I’m seeing the same thing today

That page has never existed, AFAIK. We just don’t allow the repo to be browsed that way. Is it causing problems?

well, my nexus server can’t access it either. Should it be using a different URL?

The server is there, it’s simply not browsable and there is no landing page as Sterling mentioned. If you are proxying the server with Nexus you’ll have to disable the connection validation and it’ll work.
