Here's the situation.
I have an EC2 Ubuntu instance (henceforth called the server) running a few websites.
I have a home network of two computers:
- The desktop PC is connected to the router (via a wired connection).
- The laptop is connected wirelessly to the same router.
Both computers run Windows 10.
I'm trying to upload an image (a .jpg photo) from the desktop PC to a website on the server (via the web interface). It starts uploading for a few seconds then stops and never completes the upload.
However, I can upload the same file from the laptop (which is presumably in the same network as the desktop PC) without any issue.
If I try to upload that file via FTP from the desktop PC, the transfer times out.
But from the desktop PC, I can upload that same photo to Facebook or other website without any problem, so I guess it's a combination of this specific machine with this specific server that's having an issue, though I am completely clueless as to where I should investigate to solve the problem
(Note that transfers from the desktop PC to the server used to be fine, but I can't really tell what's changed since it stopped working)
Any lead for where I should look?
Thanks in advance.
