Progress upload hangs when uploading files

[David Kwaw]

I have an upload issue which I can re-create all the time.
If I upload any file (artefact/file/index.php) using the drag and drop files method, the progress bar hangs and never disappears but the file uploads eventually, refreshing the page confirms this.
If I use the 'Choose files' button, I do not have this issue.
In both cases clamav is activated. If I deactivate clamav the 'drag and drop files' method works.
clamav finishes it's scan for the files I have tested, I can see this when I monitor the running process.
I am not sure how to resolve this issue, both my dev and prod instances experience this issue, please can anyone shed any light on this? Thanks.

Hi David,

Can you please say what you mean with 'progress bar hangs'? There is no progress bar, i.e. a bar showing how many percent of the file have been uploaded. There is only the spinner / loading icon, i.e. a circle that rotates. Do you mean that?

Do you see any errors in the Javascript console?

Thank you
Kristina

Hi, sorry, I was checking this space for weeks, I just checked it now so sorry for the delay in replying.
Yes my mistake, the dot circle that rotates continues to rotate.
There are no javascript errors in the console. With the same file I click on the browse button to upload and it works. Please check the image I attached, both done on Chrome Version 84.0.4147.125, top shows brows button method and the bottom drag.

Regards
David
