I have noticed that multiple password attempts on SSH don't get blocked at all. While testing the regexes, I have found that my logs choke on "^%(__prefix_line)s"

The following doesn't work:

$ fail2ban-regex \
"May 30 21:03:25 vps docker/ftps[1346]: Failed password for teresaejunior from 1.2.3.4 port 50714 ssh2" \ '^%(__prefix_line)sFailed \S+ for .*? from <HOST>(?: port \d*)?(?: ssh\d*)?(: (ruser .*|(\S+ ID \S+ \(serial \d+\) CA )?\S+ %(__md5hex)s(, client user ".*", client host ".*")?))?\s*$'

The following works (removed ^%(__prefix_line)s)

$ fail2ban-regex \
"May 30 21:03:25 vps docker/ftps[1346]: Failed password for teresaejunior from 1.2.3.4 port 50714 ssh2" \ 'Failed \S+ for .*? from <HOST>(?: port \d*)?(?: ssh\d*)?(: (ruser .*|(\S+ ID \S+ \(serial \d+\) CA )?\S+ %(__md5hex)s(, client user ".*", client host ".*")?))?\s*$'

The system is Ubuntu 16.04.4 (actually, my log doesn't match against the new regex rules of /etc/fail2ban/filter.d/sshd.conf on Ubuntu 18.04 either).
