Tectonic throws DNS error when trying to fetch web-bundle

[klingtnet]

Tectonic throws a DNS error when trying to compile a document because it cannot resolve relay.fullyjustified.net.
I'm a bit surprised that tectonic requires some external service to be online.
Anways, you can find a minimal example to reproduce the problem below:

$ cat README.md
# A Readme

Some test.
$ pandoc --version
pandoc 2.19.2
Compiled with pandoc-types 1.22.2.1, texmath 0.12.5.2, skylighting 0.13,

I was able to reproduce the problem locally as well as in Docker. My Dockerfile looks like this:

FROM ubuntu:jammy
ADD https://github.com/jgm/pandoc/releases/download/2.19.2/pandoc-2.19.2-1-arm64.deb /pandoc.deb
RUN dpkg -i /pandoc.deb
ADD https://github.com/tectonic-typesetting/tectonic/releases/download/tectonic%400.11.0/tectonic-0.11.0-arm-unknown-linux-musleabihf.tar.gz /tectonic.tar.gz
RUN tar -zvxf /tectonic.tar.gz tectonic\
        && mv tectonic /usr/bin/tectonic\
        && rm tectonic.tar.gz

[klingtnet]

I found a workaround by specifying an alternative web-bundle URL like:

$ pandoc --pdf-engine tectonic --pdf-engine-opt='-w https://archive.org/services/purl/net/pkgwpub/tectonic-default' README.md -o README.pdf

The URL was copied from this thread: #685 (comment)

[pkgw]

See #951 . The domain was expired for about 2 hours. It should be fixed now, maybe taking a few hours for DNS to propagate through the system.

Can confirm that it works again and thanks for the quick reply!

I am currently facing the same error. Is this a temporary issue?

[pkgw]

@heyarne Generally, if you are experiencing a network-related issue like this, it is much more likely that it is on your side than the Tectonic side. At the moment everything in the Tectonic web services appears to be stable and running normally.

Can confirm that it works now. Sorry for the noise!
