Yes, it is really normal when lots of people try to upload at the same time. Bandwidth is limited, so when lots of people start to run the warrior, the servers need some space to do their thing. Also, IA has limited bandwidth, so sometimes that's the bottleneck too.
If you give it time, it'll work eventually. Up the concurrency to max, so you can have more items in the upload state, as long as you don't start hitting rate limits from reddit, it'll be fine.
