Hello,
so I have this problem on my server with Resource pack. I pasted link for the resource pack in the "Resource pack URL" which is this: https://vanillatweaks.net/share\#BiiS95 and when I joined the server it asked me if I want to download it and when I click yes then it loads but nothing happens. Please help me fix this. I also noticed in log this error: [09:21:06] [Server thread/WARN]: You specified a resource pack without providing a sha1 hash. Pack will be updated on the client only if you change the name of the pack.
