I got Nextcloud running on my VPS and I want to use it like google drive to be able to have myself and aother person be able to look over and edit docs and slides.
My VPS currently only is paid for minimal use with 1 vCPU, 1 GB Ram and less than 50 mpbs bandwidth. And I noticed that when I open up files like videos or .txt docuemnts, they run, and can be edited, but when I create new or edit and Powerpoint or word document, it says it can’t be loaded.
According to AI, it looks like the issue is the lack of RAM. I’m wondering if would be worth upgrading, to around doubling the vCPU, RAM and putting bandwidth to 100 mbps, just not sure since you can’t shrink it after upgrading.
Does this sound like it would fix the problem? I tested slides out on the demo, but even that was a little slow and laggy. Is that because the server running the demo is minimal too?
You did provide your VPS specs but the support template still asks for several additional details (Nextcloud version, storage type, apps enabled, logs, etc.). Without those, the answer can only stay general.
With that said: Your current VPS (1 vCPU, 1 GB RAM, ~50 Mbps) is far below what is required for online document editing.
TXT and simple previews work, but PowerPoint/Word editing requires Collabora or OnlyOffice, and those suites will not run reliably on 1 GB RAM. They often fail to load documents exactly the way you describe.
To answer your question directly:
Yes — lack of RAM and CPU is the problem.
Doubling to 2 vCPU / 2 GB RAM is still “survival mode”, not comfortable use.
If you want stable document editing, you should aim for at least 4 GB RAM and a decent CPU.
Bandwidth is not the issue here.
The demo feeling “laggy” is normal — these office apps are heavy, and running them on minimal hardware makes it even more noticeable.
So yes: upgrading resources would almost certainly fix the loading issue, but consider going higher than just doubling your current plan if you expect a Google-Drive-like experience.
