After running 'Tailscale up --accept-dns=false --advertise-routes=10.0.0.0/24', the download operation hangs after writing to stdout;

This behavior appear to be documented on this blog.
The router is running a fresh installation of OpenWrt on the most recent firmware, other info below:

That does not look to be the issue in the blog. For some reason, tar is not able to extract the downloaded file.

Can you download "https://pkgs.tailscale.com/stable/tailscale_1.32.2_mipsle.tgz" on your machine and use tar to extract it successfully? If so, can you run the bowl commands manually on your router and share the output? How much RAM (free) does your router have?

du -sh /tmp
df -h
mount
free -mh
wget -O- https://pkgs.tailscale.com/stable/ | grep tailscale_ | head -1 | cut -d'_' -f 2
echo -e "tailscale_1.32.2_mipsle/tailscale" > /tmp/tailscale_1.32.2_mipsle_files.txt
wget -O- https://pkgs.tailscale.com/stable/tailscale_1.32.2_mipsle.tgz | tar x -zvf - -C /tmp -T /tmp/tailscale_1.32.2_mipsle_files.txt

That is correct behavior. It can start extracting files when the rest is still being piped, it will cause wget to pause for a while. But tar should not say unexpected end of file.

It seems when running wget -O- https://pkgs.tailscale.com/stable/tailscale_1.32.2_mipsle.tgz | tar x -zvf - -C /tmp -T /tmp/tailscale_1.32.2_mipsle_files.txt, tar reads the output directly from the stdout, sees the binary "tailscale_1.32.2_mipsle/tailscale" and begins extraction while "tailscale_1.32.2_mipsle/tailscaled" is still being outputted, and hangs from that point on.

I'll test what you mentioned above and will get back asap.

Running the command above several times does complete without problems, but when running the single line 'wget' command, it does still hang.
I'll include the commands above into the script, I appreciate your help.

It seems like the problem still occurs when running as a shell script.

Is this occasional or happens everytime? I havent had this problem in quite a while.
