Briefly describe (1-2 sentences) the Bug you’re experiencing: It looks like I’m having exactly the same problem as this person: Cant attach a file - #4 by Marie where every time I try to attach a file to a task I get a message in the lower left corner that says “Failed to attach…”
Steps to reproduce: Like that first poster, I’m not sure if this is an issue with the organizational network and blocks or something else.
Browser version: Tried Chrome and IE

Hi @Vonnie and thanks for reaching out!
Is this happening when you’re attaching something from your Computer? Dropbox? Google Drive?
Can you confirm if this is happening with every attachment you’re trying to add?
Is this an issue you can reproduce with multiple project?
Looking forward to your reply!
Thanks for your response!
It’s when I’m attaching something from my computer (my org doesn’t really use dropbox or google drive.)
It’s with every attachment I try; even small image and text files
I tried creating a new project and it happened there, too.
So sorry for the trouble and for the delay in responding to you!
