Timeout when using pmtiles extract

[megansmith-1]

I'm trying to do a partial download of the PMTiles map so that I can host it on Firebase. However, I repeatedly get a TCP timeout error.

The code I give it:
pmtiles extract https://build.protomaps.com/20260115.pmtiles basemap.pmtiles --bbox=-30,42,30,65

The response I get:

2026/01/15 17:16:48 extract.go:373: fetching 258 dirs, 258 chunks, 12 requests

To debug, I tried this with smaller bounding boxes and the only one I could get to work was bbox=-1,-1,1,1 which equated to downloading a 980kB file in 2 seconds. Since this is super small I thought maybe there is bug?? If not, what is the best way for me to a partial download? I could download the whole file but that seems a waste of bandwidth since I want at most 25% of it and I also need to then upload it to my firebase bucket which tends to be slow.

Thank you in advance!!
