Is the server down?

I was trying to use tectonic for my tex file and and it looks like I can’t connect to the server. is the server down?
I had no issues using tectonic yesterday.

This is the output I get.

$ tectonic main.tex

I’m also having this exact issue, so it’s not just you. On my computer, it keeps retrying, but the server is returning a 404 so I’d expect it’s not something that will be fixed by trying again. I’m on Tectonic 0.1.15.

I’m not sure if the problem was fixed on the server end or something I did got it working, but I am able to compile PDFs again. In case anyone else is still having the problem, I installed texlive-most (, used pdflatex to compile my document a few times, and now it works. Perhaps it found the dependency on my computer instead of looking for it online?

I did not do anything, but it started working for me too.
the links in the errors are not giving a 404 now.

If somebody fixed the server, thanks!
