Can´t upload manga

[JustaName78]

Hi, I'm trying to upload 2 chapters from "Hataraku Saibou Black" and Its says that something went wrong with the upload. I already added some chapters with the same format and I didnt have any problems, the chapters also weight less than 100mb ¿What could be the problem?
