FYI I just opened a new bug report "FTP tests of test_urllib2net fail on Travis CI: 425 Security: Bad IP connecting".

---------- Forwarded message --------- From: STINNER Victor <report@bugs.python.org> Date: mar. 4 déc. 2018 à 23:08 Subject: [issue35411] FTP tests of test_urllib2net fail on Travis CI: 425 Security: Bad IP connecting. To: <vstinner@redhat.com>

New submission from STINNER Victor <vstinner@redhat.com>:

ERROR: test_ftp (test.test_urllib2net.OtherNetworkTests) (url='ftp://www.pythontest.net/README') ERROR: test_ftp_basic (test.test_urllib2net.TimeoutTest) ERROR: test_ftp_default_timeout (test.test_urllib2net.TimeoutTest) ERROR: test_ftp_no_timeout (test.test_urllib2net.TimeoutTest) ERROR: test_ftp_timeout (test.test_urllib2net.TimeoutTest)

It seems like Jython has a similar issue: http://bugs.jython.org/issue2708
