It depends a bit on the options you use. But in general, use --tries=1,
so that wget returns on error. Then restart wget (best after a pause
like 10s or 1min). If you don't use -O/--output-document, nor -c nor
-nc, a new file will be created. If you use -O, you have to adjust the
file name by yourself.

In bash it would be like

while true; do
  wget ...
  sleep 10
done


If you are a bit into the C programming language, this might be
interesting for you:

https://gitlab.com/gnuwget/wget2/blob/master/examples/getstream.c

That libwget example also understands streaming meta file (.m3u, .ram,
.wax, .asx, .pls, .xspf) and prints title information to stderr (while
the audio stream goes to stdout). With some small changes, you could
restart on error with output to custom file names.
