FTP admin 502 gateway
« on: March 28, 2023, 01:47:28 AM »
Hello,

I want to upload large files through the ftp admin mode but the system does not allow me to generate the following error, previously let me perform the action but now tells me the following and the upload size is not the problem, as it is configured for 20Gb

500 series errors are usually timeouts or connection errors between the client and server.

Really large file uploads are a bit dicey -- if the connection gets interrupted at all, you wind up with partial uploads. So if you don't have a means to resume (via an FTP client like Filezilla or whatever), you won't succeed. I've tried to upload and resume 20+GB VM images and never gotten them succeed until I changed connections to a rock solid, stable fiber link.

But if you absolutely need web uploads, you may need far larger PHP timeouts -- execution time, upload sizes, post sizes, etc.
