Cert order fails with error "During secondary validation: Incorrect TXT record"

[stevenzhu]

Hi,

@ArikS

Does Error “During secondary validation” indicates that an initial LE validation was successful, and a second validation from a different LE server failed?

I think this is because of Let's Encrypt's mutli-VA validation.
Let's Encrypt might found an old DNS query when attempting to validate your record (might be from a different server).

The best way to mitigate might be waiting longer before attempting to submit / validate order to give more time for DNS propergration.

Thank you
