My messages do not get entered.

This has happened a few times, where I get onto my computer to comment on something, I write out a lengthy comment and hit enter and the message is gone, no where to be seen. it's happened twice in the last week. I don't see any glitches, no weirdness in how the site. My well typed is now gone and a good 15 mins of my time wasted. Super frustrating when I am entering in some good feedback for my wonderful discord group.
