I just try to update the avatar, but it just request timeout error, and shows popup that connections is not ok.
Can you take a look at the response of the
/api/post/upload request in your browser console?
Do you see any errors for the /api/post/upload request when you upload something.
@patrick-anderson It should be on the network tab of your browsers console. Try uploading something while the network tab is open and it should show you the failing request. Then you can check what the server has returned in the same window.
