Pack update fails to download modpack zip

[Hobo Joe]

When trying to launch this modpack, I get asked to update, as expected - but when I click yes, the dialog simply disappears and nothing downloads. I am able to download the .zip through my browser without issue, so it's not a problem on the file hosting side. Restarting the launcher has no effect. Any ideas?

[Amaxter]

Is the pack zip named modpack.zip, and what archiving program do you use?

[Hobo Joe]

No. This is the URL to the zip: http://bmrf.me/download/BMRF-Progress.zip

And I use 7zip. Never had problems previously until I tried to do an update last night.

E: Just found this in the log:

[Amaxter]

It needs to be named modpack.zip

[Hobo Joe]

Changing the name of the zip doesn't make a difference. I've been using this same zip ever since Platform started without an issue.

[Amaxter]

Trust me, with the new launcher it does. I made the same mistake as you thinking it would still work and it didn't. It refuses to unarchive the zip unless it is named modpack.zip.

[Hobo Joe]

The problem isn't unarchiving, it's downloading. I tested anyway to make sure, calling it modpack.zip made no difference. As I said, I've been using zips named things besides modpack.zip for several months on Platform, and it's never been a problem.

[TwoTails]

Trust me, with the new launcher it does. I made the same mistake as you thinking it would still work and it didn't. It refuses to unarchive the zip unless it is named modpack.zip.

no, the name of the zip doesn't matter, just look at the derectdownloads for my packs:

http://download1487.mediafire.com/fcpjm8ptj9fg/euw70hd2n11f9k0/pokemon+for+masters.zip

http://download1645.mediafire.com/vbo8f6v3o0pg/2q77ul4dp7ozan1/grand+theft+craft.zip

http://download1649.mediafire.com/azku1vvxa64g/veb2tw8rccy9s35/Adventure+with+the+finest.zip

see? none of these are named "modpack.zip"

[Amaxter]

Hmm.. Seems your pack isn't properly set up. DId you download the forge universal jar and put that in the bin?

[Hobo Joe]

This has nothing to do with the pack itself, it's the launcher. It fails to download the zip. Besides that, the pack is set up properly. Like I said I've been using Platform ever since it started, I know how to put a pack together properly.

[CanVox]

Do me a favor and link me to your platform page so I can follow the process through from the beginning?

[Hobo Joe]

It's in the OP, but I guess a hyperlink is too subtle: http://www.technicpack.net/modpack/details/progress.12299

[CanVox]

Hi, Hobo Joe, here's what's going on:

Your zip file has been moved to https://bmrf.me/download/BMRF-Progress.zip

When you access the file through the browser, your browser receives the 301 code and then automatically downloads it from the new location. When the launcher attempts to download it, we download the "document has moved" HTML page that has been served and then attempt to open it as a zip file, which fails. I hope this helps!

[Amaxter]

So basically you need a file host with actual direct links, DropBox is okay for small packs, but I find copy.com is great (but a little slow) if you need the extra bandwidth for free.

[CanVox]

In hobo joe's case, his file host works great, it just wants downloaders to use the HTTPS address for security reasons. I'm not sure why our HTTP URL Connection isn't following the redirect- it's configured to do so- but it may be that it doesn't regard "301 moved permanently" responses as redirects per se.

[Amaxter]

Oh, I see.

[Hobo Joe]

Works like a dream, thanks very much CanVox! I don't think I ever would have found that myself.

[CanVox]

No problem, we're making a pass to improve error messages on the new launcher soon, I'll make sure that redirect issues like this are called out more prominently.

[TheWolfram]

For anyone else having this issue and you are using either a private pack or a custom pack, and if you are using dropbox as your host, make sure you replace this- https://www.dropbox.com/ with this- https://dl.dropbox.com/ for your modpack location
