Issue "struct.error: unpack requires a buffer of 4 bytes" -- API Token

[Christophe Gevrey 13]

Hello,

Today I have an issue. I cannot get my dev API to work.

It started with:

struct.error: unpack requires a buffer of 4 bytes
Traceback (most recent call last):
  File "/home/cri/dev/_python_modules/evernote_lib/evernote_lib_test.py", line 15, in <module>

    val, = unpack('!i', buff)
struct.error: unpack requires a buffer of 4 bytes

I wanted to check my Developer Token. but the page "https://www.evernote.com/api/DeveloperToken.action" is returning "HTTP ERROR 503"

Can somebody help? 

Is it an issue on my side or on Evernote's side?

It was working 2 hours ago.

Thanks.
