[litetex]

Same error here.
Looks like this was blocked by cloudflare (maybe "under attack mode" active?): I'm getting a challenge as HTTP answer on my server...

[calvinli723]

Similar error also happens to me when using share code.

[itzg]

I'm starting to wonder if they're disallowing automated access and instead requiring usage via their website...

[itzg]

FWIW using a sharecode worked fine for me using:

services:
  mc:
    image: itzg/minecraft-server
    environment:
      EULA: true
      VANILLATWEAKS_SHARECODE: KcuEN2
