Server not prompting players to use the resource pack

I've been trying to start a server using the map 'Mazescapist', but no matter what I try the map's texture pack will not load, and noone who joined would even get prompted to use it, what do I do? I have tried creating the dropbox link to the resources file and putting in the sha1 code (all lowercase).

Share the entered dropbox link.

Which software and version is installed on the server?

Here is the dropbox link and sha1 code I put in

I have the server on vanilla minecraft 1.16.5

Please try to delete the server list entry in your in-game server list and add it again

It didn't work, I even closed Minecraft before reopening it and re-adding the server.

What is the address of the server in question?

the server address is Maze_escape.aternos.me

Quote from Roman

The link entered on the options page has dl=0 set?

I just checked, and yes, I must have forgotten to change the 0 to 1, but when I changed it and checked, removing the server from my server list first, nothing changed

The pack was probably not created 100% correctly.

While such packs work on single-player Minecraft is more strict with server packs.

Unfortunately I'm not familiar enough with resource packs to tell you what exactly is invalid.

Alright, thank you anyway.
