curl -L "https://github.com/versatiles-org/versatiles-frontend/releases/latest/download/frontend.br.tar" > ./frontend.br.tar

versatiles serve -s ./frontend.br.tar -p 8080 "pays-de-la-loire-shortbread.versatiles"

The error

When going to http://localhost:8080/map.html?url=/tiles/pays-de-la-loire-shortbread/#13/47.2383/-1.5603 (Nantes, in the middle of the tiles data area), I got some 404 for all tiles.

Trying to sort out things, on OpenStreetMap.org, I get https://tile.openstreetmap.org/13/4058/2873.png for the area pays de la loire, so I expect http://localhost:8080/tiles/pays-de-la-loire-shortbread/13/4058/2873 to work but got a "Not Found"

Whereas if I try the opposite e.g http://localhost:8080/tiles/pays-de-la-loire-shortbread/13/2873/4058, it works but it's not the pattern I expect and I know now why I got these 404 errors.

Any obvious idea about how to solve the issue?

Issue below solved by using more older version with cargo install --version 0.2.13 versatiles instead of the current 0.2.14 because of fix on server side e.g https://github.com/versatiles-org/versatiles/commit/bba05ade7be1fb6a1f989229a947857b7921ddd1

Unfortunately, then, got another issue with error on client due to gzip with error {message: 'Unimplemented type: 3'}.

The other issue: whereas versatiles probe pays-de-la-loire-shortbread.versatiles was mentioning tile_precompression: Uncompressed but if doing

curl "http://localhost:8080/tiles/pays-de-la-loire-shortbread/14/8121/5749" | file -

it returns /dev/stdin: gzip compressed data, from Unix a compressed tiled "uncompressed"...
