Error getting challenges: urn:ietf:params:acme:error:malformed

[stam]

I'm running the command:

acme_tiny \
>           --account-key /var/lib/https-portal/account.key \
>           --csr /var/lib/https-portal/redacted.domain/staging/domain.csr \
>           --acme-dir /var/www/default/challenges/ \
>           --disable-check \
>           --directory-url https://acme-staging-v02.api.letsencrypt.org/directory > /var/lib/https-portal/redacted.domain/staging/signed.ongoing.crt

Which gives the following output:

Parsing account key...

I'm not sure how to debug this

I'm seeing similar errors in this thread: https://community.letsencrypt.org/t/problem-with-renew-certificates-the-request-message-was-malformed-method-not-allowed/107889

Which points to this thread as the underlying issue: https://community.letsencrypt.org/t/acme-v2-scheduled-deprecation-of-unauthenticated-resource-gets/74380

@stam it looks like you're using an old version of acme-tiny. This issue was fixed in https://github.com/diafygi/acme-tiny/commit/1b6c6bc0e67aa28fac259c3077883594d3c871d5 and released in 4.1.0
