Why can't I use SSH anymore?

Why can’t I use SSH anymore? It first worked, but then it showed “SSH is not allowed for this project” or “SSH is not allowed for this user” too, but I don’t know why, please help ;D

Hi @EiskalterFreund welcome to the CircleCI Community! This error usually occurs when there has been a change of settings on the project or organization-level. We would like to take a closer look at your account, could you submit a support ticket with your GitHub or Bitbucket username so we can investigate further? Looking forward to hearing from you!

Ok, I will do that ;D.
