Since the POODLE attack, SSLv2 / SSLv3 is being phased out on most websites and the only way to make iBrowse and AmiSSL work with websites over HTTPs is to set the default SSL client to TLSv1. This can be done by issuing:
setenv AmiSSL/SSL_CLIENT_VERSION tls1
followed by:
copy ENV:AmiSSL#? ENVARC:
to make the changes permanent.
