Issue with uploading pages for a chapter

[BefuddledFettuccine]

I am very new to the whole scanlation thing (I am trying to upload my first chapter to Mangadex as I speak), but I am running into an issue where the last few pages of my scanlated chapter are seemingly not uploading in the menu before posting the chapter. The spinning wheel loading thingy keeps on going, and has been doing it for the last 5 pages for a good 20 minutes now, and I'm not sure what to do. I have deleted each of the pages and tried re-adding them to the upload, but the issue still persists. I don't believe my internet is the issue, and I can't think of any other reason for this happening, especially because the first 36 chapters uploaded perfectly fine in like 2 minutes. I've even hit the orange upload button but now its just greyed out and nothing has changed. I'm not really sure what else to do?

Nevermind. After 4 attempts of fully reuploading the entire chapter, all the pages finally managed to get uploaded. I guess it might have just been a basic internet or system error, but I managed to get it working in the end.
