My instance’s first member suffered from the “We cannot detect if your account was created, please ensure you have cookies enabled” message while signing up, which is accounted here: We cannot detect if your account was created, please ensure you have cookies enabled
I spent a hour reading that topic, and finally realized that the hash boxes are some canary logic. Successfully reproduced the “We cannot…” issue by editing that hash for even a character. Maybe it will be fixed too, by hiding that challenge boxes. 2-in-a-row.
I found another instance that is affected(https://discourse.jupyter.org/) and now I’m surprising about how instances could be remotely affected, even if I didn’t change things after I successfully signed up with no issue.
I’m not sure that ./launcher rebulid app automatically pulls the latest commit that broke signup, but I think I did rebuild instance to install some plugins before the issue was present. Maybe this is the cause.
