Subject: fix issue with openssl
X-Git-Url: https://code.communitydata.science/nu-vpn-proxy.git/commitdiff_plain/4b02c05b544927f4669c6d98fac1124080c93df2

fix issue with openssl

The scripts seem to be relying on a legacy openssl renegotiation
protocol and this allows it to continue. I don't know if this a
requirement on the NU side or a feature of these scripts but this
works around it in the shorter term.
