Rocket Chat - File uploading stacks at 0%

Question

I'am trying to upload file into a channel. But nothing works. File uploadings stacks at 0% and not progress more.

Steps to reproduce:

1. Open any channel.

2. Upload any file or files.

3. Click submit button.

Expected behavior:

File completely uploaded and message successfully sent.

Actual behavior: Stacks at 0% of file uploading.

Somebody knows whats wrong?

Thank You.

Answer 1

Please check if Site URL under general settings points to the public url of the application. I have seen instances where the upload is stuck when site url is incorrect

Answer 2

My roadtrip:

1. Change on File Upload the Storage File System
2. Set /tmp/ufs folder
3. chmod 777 on folder /tmp/ufs
4. Disable Protect sent files
5. Change Site URL to the same that you access.

Works perfect for me.

Answer 3

You have to make sure that Site URL matches the public URL. If you don't want to do this manually every time, make sure you set ROOT_URL upon deployment.

Answer 4

Check that your "site url" setting is httpS if your site is.

In my case (docker version) I could use rocket-chat messages with a non ssl "site url"

http://example.com/chat

changing it to https allowed file upload

https://example.com/chat

The setting is under

Administration/Settings/General/"Site URL"
