Hi @lexfrei,

Thanks for your interest in Traefik!

I cannot reproduce the issue with the same configuration.

Can you check your token?
Maybe you can try with another token?

We have found and fixed the problem: yesterday one of our internal tokens expired, which produced an error while downloading the plugins. The problem is now fixed.

Thank you.
