Just a few days after the last time this was fixed, the same problem with the "Upload failed! (-1)" message I was having before with uploading an updated version of my project to Realms has come back to strike again. I have tried closing both the game and the launcher and reopening them again, and I haven't even budged past 0% uploading progress without seeing this message getting in the way...

You don't need to report the same issue thrice, we know it still keeps happening.

What should I do if I run into it again (which I unfortunately have done again)?
