Hi. New here and need help.

I want to download some large files (GBs) and have limited Peak Data (60GB/month) , so I want to download in the wee small hours, where I have 190 GB/ month of data.

My problem is that if I try to schedule for those hours, I keep getting error 403 access denied. If I schedule for an hour from my "now time", to test the access, it works.

This is one of the URLs that I am trying to access.

https: //cakewalk.s3.amazonaws.com/estore/SONAR/Shared/MelodyneEssentials_2.1.2.002_1.0.0.7.exe?AWSAccessKeyId=AKIAIT3GFEECTPLZLU4Q&Expires=1622646067&Signature=rB6d5UveeizeAv5nYjrdJEhBypM%3D

Does that "Expires=1622646067" mean something? Is that some sort of time signature? I tried mS but that was 450 hours.

Or, instead of jumping about offering "solutions" to my own problem ....has anyone any of an idea if there is a clue to my problem in the url?

Any help appreciated

I'm betting that your AWS key / session is expiring. For example, I tried your example URL and got a 403 immediately in FDM.

It sounds like you need to figure out how to get a persistent AWS key / enable a persistent session, or else get access to one that lasts longer.

One thing that might work is to try to schedule them within 1 hour of the actual off-peak hours, but I suspect it's not that easy, as that may be too late for a normal working person to stay up to schedule.

If 1 hour works, try 2 hours. If that works, try 3 - basically, figure out what the maximum key TTL / session alive period is, and see if you can get those downloads scheduled within that time for the off-peak hours.

As you can easy guess, this is temporary link. Parameter Signature probably passes SHA1 hash of the file, parameter AWSAccessKeyID ia a unique ID of the download task.

Parameter Expires passes Unix timestamp, in your case it's "Wed Jun 02 2021 15:01:07 UTC+0000" (expired) . See also online converter: https://www.unixtimestamp.com/

There are some possible issues:

1. If you have got the link by email, you should start download (and possibly finish it) before the link expires.

2. If the download link is generated online, there may be two expire timestamps: for download start (unknown) and for download finish (passed as Expires). In such cases you should start download as soon as possible (for example, in 5 minutes - before your connection session expires) and finish it before the link expires.

3. Unique ID may base on your credentials and IP address. If you pause download and want to resume it later, your IP address may change on Internet reconnection and you won't be able to continue download.

The best solution would be to start download ASAP and set FDM to snail mode to keep connection active. You can also set slow mode (for example, with traffic download limits set to 128 KB/s) as your peak limits aren't so radical (60 vs 190 GB). Unfortunately, FDM doesn't support traffic usage mode scheduling so in this case you have to change traffic mode manually when the peak limits end.

You might also want to read up on what 403 Forbidden Error means. As I read it also says:

The vast majority of the time, there’s not much you can do to fix things on your end. Either you’re really not allowed to access the resource, or there’s an error on the server side of things. Sometimes, it’s a temporary error; sometimes it isn’t.

So at this point you will have to contact the site your trying to get the file from to resolve the issue. Tried that link and that sounds like a firewall blocking my attempts to open the url and at this point that is something between the site and yourself to resolve.
