ClientError: Response 500

[d0x7]

I was trying to request a new certificate, which didn't work using imap/smtp. Nothing happened, no output whatsoever (besides the "you're requesting a cert [...]" header), and then after around 5 minutes, I got a An unexpected error occurred: ConnectionResetError: [Errno 54] Connection reset by peer.

Then I thought I would try the interactive mode, which just game me An unexpected error occurred: acme.errors.ClientError: <Response [500]> instantly.

Are there any known issues or what am I doing wrong? I cloned the repo, installed it as per README and then basically used the example command (obviously with my own imap/domains). I had a typo in the password which also instantly tripped an wrong password error, but after correcting, the above happened, so nothing for around 5 mins, then the first error.

Have a good day :)
