What the title says. I try to post to a topic, picture and text, and I get a 400 error code.

I used to get 400 errors when posting pictures. I eventually tracked it down to image size. If I shrank it to under 500Kb it went through every time. Sometimes a little larger would go through but every picture under that made it.

That might be it. I tried clearing the app cache, and it still wouldn't go through. I can obviously make posts. The image was the problem.

Some instances have a pretty low limit for picture sizes.

I only ever had an issue when I was trying to upload an image. Text only posts were just fine.

I've had similar problems and this was the issue. The problem is there's no way to know what the requirements are from a user's point of view at the moment of posting, and the error doesn't provide useful information, so it just looks broken.

I don't know how much can be done within the app about the error messaging, but having a way to squish down the image in size and compression within the posting flow would be really helpful.

I have an app for combining two images into one. I found that just putting one image in it and saving almost always does the trick. Though, rarely, on some already small files it will actually make them bigger. But since I already use it it comes in handy instead of having to install a new app for that.

I agree. It's fundamentally broken. 400 is useless. And when I searched I found zero clues. I even posted about it and got zero clues. Had to figure it out on my own.

Are you able to create posts with WebUI?
