I'm trying to upload one file, (2.5 MB) to a specific website but I receive an error message saying "Gateway Timeout".
I don't get this message for files that are smaller, for example files that are 300 KB.
I also can upload files larger than this size (2.5 MB) successfully on other sites, like youtube.com etc ...
When we don't use proxy between the upload goes well. I have to mention that the IP web proxy is behind a Checkpoint Firewall.
I know that only with this information it's not possible to solve the issue but if someone can suggest me some topics how to troubleshoot this problem,
I would be very gratefull.
Thank you and best regards,
