Additional info:
Comment 1 Nikos Mavrogiannopoulos 2016-12-19 10:24:53 UTC 
Although the underlying issue is the fact that wget overwrites the system policies with its own which are more lax, the functionality issue (connection problem #1405956) can be fixed in gnutls [0]. I will include it to the next rebase of the component.
