I'm trying to upload a file but I get an error message like the following:
https://sapco.nyc3.digitaloceanspaces.com/b3vcchphzgj5m8p6ld51yk7867uu?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=QTHCA5KKQUHAKMMATAIP%2F20200503%2Fnyc3%2Fs3%2Faws4_request&X-Amz-Date=20200503T214158Z&X-Amz-Expires=10800&X-Amz-SignedHeaders=content-md5%3Bcontent-type%3Bhost&X-Amz-Signature=7b77a0f1551a262586980b709fdc44a2bc173ab6ae7279385e831493b1d13e53

How can I debug this further?
So far I have tried:
Resetting my Access and Secret keys.
At first I thought this was related to PWA-related work, but I migrated to an earlier branch and have the same issues.
Tried different files: each have the same error.
Happens both in prod. and locally.
Update 1: This randomly started working again on production. However it's still broken locally.
With the same file I have the 2 paths for the PUT request that leads to the error above.

The issue must be related to the way X-Amz-Signature is computed.
Digging further with bundle open activestorage I can see it's roughly here. https://cutt.ly/6yjc7u1
I verified the Content-Length and Content-MD5 are both the same (vs local and prod). (123803 and ujNHxwCuwZ1mak927GUX3g== respectively).
Update 2: I tried this in Firefox with the same image and no problem locally. There must be something fishy going on with the cache. I then tried an Incognito window and that also seemed to work. Finally, I did a hard refresh in Chrome and now I've unblocked myself. Didn't quite figure out what was going on but leaving a final piece of information for anyone else:

Hard refreshing resolved the issue.

when investigating network behavior, I usually use postman for sending HTTP requests, however
I need the option to send a raw HTTP request (via clear text), or at least only the headers, and it seems that postman does not support to edit your request via clear HTTP text. (buy the way the opposite is possible, you can read the raw http text of the requests you constructed in postman but you can't edit them)
for example:
Accept: text/javascript, text/html, application/xml, text/xml, */*

does postman allow editing the raw HTML? if not, there is other tool that can?
My (working) code looks as follows:
<script type="text/javascript" src="../AAAA/1111.js"></script>
<script type="text/javascript" src="BBBB/2222.js"></script>
The headers I see on the server side are:

How can I tell the path (on the server side) since they both look the same? One is below the referer and the other is in a sibling directory to the referer, yet I can't tell from the HTTP header. The ".." info seems to be lost yet the server gets it right? How does it know?
Thanks!

That's because the browser resolves relative references. See Section 5 of RFC 3986 for details.
So no, you can't tell these apart on the server.
I made an HTML page with some JavaScript that works fine on my laptop on Linux, but fails when I upload it on a Windows server. I think it is a header issue so I am not writing the Ajax code, but the request headers :
Ajax Request :

What should I set the headers to?
If you actually read the description of status code 406 you'll quickly find out that the problem is likely caused by "accept: undefined".
Despite what the title may suggest, this is not related to the common "preventing double post request" issue.
In my application, I add some data on outgoing HTTP traffic, and with some some websites, I randomly encounter an HTTP POST request that has a double-header, resulting in a server termination, as I assume the server doesn't understand the request and decides to cut me off. As the title says, I'm literally seeing two POST headers in a single request. This only happens when I append some custom HTTP fields to the header. For example, I came across this today when I followed a surveygizmo.com link, as seen in the trace at the bottom of this post.
I cannot understand if it's the browser that's doing something funky because it noticed I've modified some data, or it's something in my LSP application that causes this to happen.
When I debug my application, I only see the intercepted request the first time, which is when I inject the custom data. After that, I don't see the request anywhere except in Wireshark, so it's not like I can remediate the double headers by deleting the redundant data.
Things to note looking at the trace:
The data I'm appending is 'Custom-FieldN:'
Two almost-identical headers
Three double-CRLF's in one single request header (how is that possible?)

What part of the header gets parsed by rewrite engines? (I mostly concern about Nginx)
The GET part, that is, /resources/css/jquery-ui.css in your example.
