So today I came across this issue where my friends were suddenly unable to download my custom modpack this morning. Keep in mind I have not updated or changed anything about the modpack, it just stopped working. I attached the error in an image and this occurs when my friends try to update or download the modpack. Weirdly enough it does not affect me and I am successfully able to update my modpack. Any help understanding this error would be appreicated. Also I tested the download link of both dropbox and onedrive. The same issue persist.
