Error when assembling chunks, status code 504

Hi, I was uploading 12 1.1GB files and got errors like the above. Most files seemed to upload but a couple were only partial copies. I was uploading via my Firefox browser. It sounds like this nextcloud issue (https://help.nextcloud.com/t/error-when-assembling-chunks-status-code-504-on-big-file-upload/99912/1). Could somebody please look into this? If I can’t upload large files to the cloud it somewhat defeats the purpose of having a cloud account for me.
