    I'll assume the log is the one where the connection failed.

    This means either the username or the password in the ISP's database
    doesn't agree with the one you have in pap-secrets. If you didn't
    change them in that file then it's likely that the ISP changed
    something that caused the authentication failure. The change may
    be unintentional, e.g., a result of a database change or update,
    or it could be intentional.

    If it's intentional then you may have violated their acceptable use
    policy, not paid your bill, ect. In either case you will likely have
    to talk directly to the ISP to resolve the problem.

    It's remotely possible that a change in the PPP implementation at the ISP
    caused the problem. For example, some PPP implementations are broken
    with respect to asyncmap negotiation and you will need to request that
    the ISP set the same asyncmap that the ISP requests you set. You can
    try adding "asyncmap a0000" as a pppd option, the most common case in
    such a problem.

    You can also add the pppd "debug" option and get all the PPP link
    negotiation messages by following this recipe:

    Add the line
    " local2.*;*.=debug;*.=notice /var/log/ppp-debug.log "
    to /etc/syslog.conf, and do " kill -HUP `pidof syslogd` "
    so that syslogd rereads it.

    One place to add pppd options is /etc/ppp/options. Post an exact copy,
    including timestamps, of the log if you what to see whether anyone here
    can spot something that might cause the problem.
