We couldn't save your attachment for 1 user

Hey! 

We are facing the following issue:

1 user tries to upload 3 png files with 100kB each to the issue. The first one uploads fine, while for 2 others he is seeing the "We could not save your attachment" error. It does not matter from which file we start first.

On the new issue, screen error is not being displayed, while the 'Create' button is changed for endless spinner instead when he tries to upload more than 1 attachment.

I have tried to do the same from my side with those 3 files and all works fine, which tells me, that issue is not with file size. We tried to clear cookies for him and try again, however, this did not help.

Any ideas on how to fix this?
