Sage secure notebook: Failed to load application: [('PEM routines', 'PEM_read_bio', 'no start line')

[Ceno Byte]

I managed to get the latest version of Sage compiled with openssl, however whenever I try to run notebook(secure=True) I get this error:
'
OpenSSL.crypto.Error: [('PEM routines', 'PEM_read_bio', 'no start line')]


Failed to load application: [('PEM routines', 'PEM_read_bio', 'no start line')]



sage: version()
'SageMath Version 7.1, Release Date: 2016-03-20
Ubuntu 16.04

I have no idea how to fix this and would like to both find an answer and distribute it to others
I'm not a programmer, I'm a mathematician.

Thanks in advance

Could you quit Sage, remove the directory ~/.sage/notebook/
and re-start Sage, as recommended in
