The mailing list for listmasters using Sympa

["O, Victor" <address@concealed>]

I think at some point Sympa started requiring a host header be passed in the request that matched whatever domain is listed in your sympa config (/etc/sympa/sympa.conf)

I’m not sure which version but I believe it was something within the past year or so. A page with a mismatch host header returns a blank page with that 421 http response. This is from my own personal experience anyhow.

Subject: [sympa-users] How to debug web interface failure?

 

Sympa users,

I installed sympa a year ago with the intention of migrating from
mailman 2.  I never finished the project, but now I'm forced to abandon
mailman 2, so I must finish this.

Machine is running FreeBSD 11.4-RELEASE-p9 i386.
Apache24-2.4.48 (FreeBSD package revision of Apache 2.4)
mysql57-server-5.7.34 (which sympa seems happy with)
sympa-6.2.62 (latest FreeBSD package)

I had everything working -- web interface and the ability to send emails
that passed gmail's DMARC tests.

Now, however, I find the web interace returns an entirely empty page.
Nothing at all.  I can still send emails to my "test" list, so Sympa
is still "working" as a mailing list.

The web access_log file shows this:
98.109.205.15 - - [28/Jul/2021:22:45:18 -0400] "GET / HTTP/1.1" 421 1
98.109.205.15 - - [28/Jul/2021:22:45:28 -0400] "GET / HTTP/1.1" 421 1

There are TWO lines for every attempted access.

All attempts to access the web interface return a blank page and show
a 421 code in the log file.

(Yes, that's my own IP).

The error_log file has no new entries at all.

How do I debug why the web interface is broken?  It worked, I ignored it
for a year, and now it's broken.  There have been no changes to the machine
other than regular security updates from freebsd.org.

Thanks,
