I had an issue upgrading from django 1.8 to 1.9 in a site with ssl. The site was giving SSL_ERROR_INTERNAL_ERROR_ALERT from time to time.
In apache logs appeared this kind of errors: [ssl:warn] [pid 26704:tid 140422937700096] AH01990: PRNG still contains insufficient entropy! extern "Python": function Cryptography_rand_bytes() called, but no code was attached to it yet with @ffi.def_extern(). Returning 0. The problem was solved with: pip install —upgrade PyOpenSSL (to version 16.2.0) I don't really know if it was because my enviroment (vps), but I let here this note as it was hard to find information in internet about it. -- You received this message because you are subscribed to the Google Groups "Django users" group.
