I am not sure how to do that.

Can you check the TLV of the received certificate to see if there is a
FreshnessPeriod?
You can inspect the packet TLV using ndn-dissect from ndn-tools
<https://github.com/named-data/ndn-tools> .
Best,

Hi,
Everything is now updated to the latest version from source. I am receiving
the certificate but ndncert-client crashes with the following error:
terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error>

what(): Cannot parse replied certificate
Aborted (core dumped)
Best,

Hi Nikos
There has been a packet format change related to ForwardingHint and
Delegation.
Your ndn-cxx, NFD, and ndncert versions are incompatible, which causes
decoding error.
Please install all from https://nfd-nightly.ndn.today or all from latest
source code.
Do not mix different versions.
See NFD-nightly instructions for how to switch between installation methods.
Yours, Junxiao

I found it.
I can see the challenge in the log file. I enter the correct challenge and
then ndncert-client outputs:
>> Certificate has already been issued, downloading certificate...
>> Interest timeout
In the nfd output I see the following:

Any clue?
