I'm revisiting an issue we had three years ago and wondered whether anyone here might have suggestions of possible causes (with testing ideas if possible). We have a work-around but my curious mind has not been satisfied.
At work we use some temperature and humidity data loggers. The units (model iTHX-SD) are accessed via ethernet and have a web server that allows the user to download data covering a day, week, month or year, saving to a text/csv file. In Oct. 2019 our weekly downloads using Chrome stopped working (around the same time Chrome 78.0.3904 was released). Chrome's download would show "Failed - No File."
Facts and testing from around that time showed:
1. The issue occurred the same week at two different facilities and with various computers, including Chrome on Win 10, Win 7, Linux and Android phone. Note, though, that only one computer attempted (and succeeded) to access the data the prior week.
2. Firmware for the loggers had not changed.
3. We could download a day's worth of data, but not a week's worth. Previously we had no trouble downloading a year's worth of data.
4. Firefox and Edge can download the data (our work-around).
5. Chrome, IE and Opera failed to download the data, with Opera reporting that the download was interrupted. (IE and Opera were not used for this prior to this test, so no idea how they 'previously' behaved.)
6. In April 2020 I tried downloading a year's worth of data with Chrome 81.0.4044 and the progress bar showed 28.4/28.4 MB for a fraction of a second before showing Failed - No File.
7. In May 2020 I was able to download a 299,599 byte file but failed with a 300,219 byte file (size based on successful download using Edge). Larger files usually fail at the end of the download but can stall late in the download.
I'd love any input on possible causes and/or tests to try. Unfortunately, I don't know (or have) the logger's firmware code. As I said, at this point I'm trying to satisfy my curiosity, which will allow me to close this out.

Thanks, @Randor. I have minimal experience with Wireshark but I did get it to log some data. I'm not seeing any apparent cause, but I'll continue looking.

If you are really getting the "Failed - No File." error in the Chrome browser then the open source code I linked shows exactly what causes the error.
As far as I can tell there are no other possibilities.

"Browser incompatibility". The server is returning (or Chrome is expecting) a code / event that only Edge and Firefox are "handling" (or ignoring) as the case my be.
I'd look at FTP.

I'm curious what the incompatibility is. As for FTP the firmware does not seem to allow that.
What I'm working on is code to submit the HttpRequest, retrieve the data, parse it and save to a database (simple steps, now that I know how to form the request). I was just hoping to get an idea of the cause in order to satisfy my curiosity.

While I'm working hard on my own card game project I found this
https://github.com/Bonifatius94/Schafkopf.AI
on GitHub.
No sample application, no description ...
I'm just wondering how somebody could find a way to use a library like that.

To be honest: Apart from your particular interest, there are trillions (?) of stuff like that out there.
You simply have to accept/skip it 
|
|
|
|
|
Obviously you find another AI and ask it to analyze the code and provide documentation for it.

To be fair and bloody obvious, ChatGPT and similar AI technology is only getting better. You can hate on it now for its lack of accuracy but in a few years its going to kick your ass up and down the street all day long.
Just saying...

By then I'll be retired, so who cares?
