I can´t upload zip in JLCPCB

Hello, I have a problem with JLCPCB.
JLCPCB does not upload any ZIP to order a pcb.
It begins to upload, but suddenly it stops at 60% and
it tells me that “Detected 0 layer”
Does anyone have a solution?

JLC issue - try again later.

I’ve been trying for a month…

You’re probably uploading the wrong zip, there are two zip files, you need the Gerber file that’s zipped.

Solved with the help of the JLCPCB chat. When unzipping the files, a “copy” ending appeared, which prevented them from being loaded.
Thank you all for the quick response and collaboration.
