 * Hello,
 * I have a feeling it’s something to do with something on the server. I think that
   may be a little out of my realm of expertise.
 * When I google around, I see this error all over the Internet, but not a whole
   lot of answers to actually what it is. This isn’t directly related, as it’s in
   reference to some other script, but I did find this:
 * > 1.9 Question: I am getting this error “error:0D0890A1:asn1 encoding routines:
   > ASN1_verify:unknown message digest algorithm”
 * > The remote connection software you are using on your server might be compiled
   > with a very old version of OpenSSL that does not take certificates signed with
   > sha256-With-RSA-Encryption into account. It requires at least OpenSSL 0.9.8o
   > for a total management of SHA256.
   > Please contact your server admin or hosting provider about this issue.

 * My understanding of the topic is limited, but I’m wondering if something happened
   recently with your host that might be a cause of this. I did read about this:
 * [http://blog.asana.com/2014/04/heartbleed/](http://blog.asana.com/2014/04/heartbleed/)
 * … which directly relates to OpenSSL. I would contact your webhost, I’m sure this
   isn’t a foreign topic to them.
