Is this the first time you’ve seen this error and can you replicate it?: Yes. This is on a fresh install.
The issue you are facing:
When attempting to upload files larger than 40MB, I get a “Connection to server lost” error and the file is nowhere to be found on the server. I can upload smaller files no problem. The max upload size has been increased to 4GB but this is failing at 40MB or more. Nextcloud is installed as a VM on a Hyper-V host. It has 4 cores and 8GB RAM assigned. The Nextcloud instance is running on a SSD array and the data store is on a HDD. When I upload a smaller file, I can navigate to where the data is stored on the HDD and I can see the file so I know that Nextcloud has the proper write access to this drive.
