SNAP Nextcloud - Slow Speed

Support intro

Sorry to hear you’re facing problems.

The community help forum (help.nextcloud.com) is for home and non-enterprise users. Support is provided by other community members on a best effort / “as available” basis. All of those responding are volunteering their time to help you.

If you’re using Nextcloud in a business/critical setting, paid and SLA-based support services can be accessed via portal.nextcloud.com where Nextcloud engineers can help ensure your business keeps running smoothly.

Getting help

In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.

Before clicking submit: Please check if your query is already addressed via the following resources:

Official documentation (searchable and regularly updated)
How to topics and FAQs
Forum search

(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can.

The Basics

Nextcloud Server version (e.g., 29.x.x):
- 32.0.2snap1 - 51274
Operating system and version (e.g., Ubuntu 24.04):
- Ubuntu 24.04.3 LTS
Web server and version (e.g, Apache 2.4.25):
- I don't know, snap manage Apache
Reverse proxy and version _(e.g. nginx 1.27.2)
- nginx/1.24.0 (Ubuntu)
PHP version (e.g, 8.3):
- I don't know, snap manage PHP
Is this the first time you’ve seen this error? (Yes / No):
- No
When did this problem seem to first start?
- Since the first installation
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- SNAP
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- No

Summary of the issue you are facing:

The download / upload speed is very slow, I tested all the ecosystem near NextCloud and it’s perfect. If I upload some files using SFTP in my LAN, everything works just fine, I’ve got 1gbps in upload directly to the hdd of NextCloud, but with NextCloud I’ve got like 60mbps. I tried to enable https directly using snap → NextCloud (sudo nextcloud.enable-https) the situation is better, I can connect directly using the LAN address (https://192.168.1.128:8443) and I’ve got 1gbps speed, like SFTP. When I turn on my NGINX proxy server to connect to NextCloud remote, the speed is capped at like 60/70mbps. I’ll attach the nginx conf that I’m using.

NextCloud is hosted in a server with the following specs:

AMD Ryzen 5 9600X

RAM: 32GB (DDR5 6000mhz)

1gbps network speed to the router (1gbps download & 300mbps upload)

Ubuntu is hosted on an SSD NVME (7000mbps speed)

NextCloud is installed with SNAP and it has two 8TB IronWolf PRO hdd with zfs mirror

If you need more details I’ll give them to you, if you could help me fixing this problem, that would be really great! Thank you so much in advance

Tips for increasing the likelihood of a response

Use the preformatted text formatting option in the editor for all log entries and configuration output.
If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Hey @Andrea_Tagini welcome to the Nextcloud community

well done! so its certainly neither a snap nor a Nextcloud issue then… more likely your reverse proxy is incorrectly configured or some other network issue

is that NGINX Proxy Manager, or ding cum NGINX? please show your configs

it seems you have not configured you trusted proxies at all:

see

and

Andrea_Tagini · December 8, 2025, 9:11pm

Hi,

thank you so much for the help!

I’ve configured trusted proxies and NextCloud works very good, also outside my home network, the problem is the speed of upload / download, not the functionality of NC. I’m using NGINX as a proxy in front of next cloud. I’ll attach the config that I’m using for NC.

Nextcloud is listening on 8400 port (http) and https is disabled

I tried to follow the guides that you sent to me, but unfortunately those didn’t work for me.

@Andrea_Tagini,

so nginx is running on the same host as the snap right?

you use the localhost ip-address instead of the host ip-address. try the host ip-address instead, also check Hosts & FQDN configuration especially this https://github.com/nextcloud-snap/nextcloud-snap/wiki/Hosts-and-FQDN-for-Nextcloud-snap#fqdn-for-nextcloud-snap-instance-vm-or-container-behind-reverse-proxy-with-termination

FQDN for Nextcloud snap instance, vm or container behind reverse proxy with termination

Setting FQDN (Fully Qualified Domain Name) is best practice and is optional on self-hosted Nextcloud snap instances running on vm or container behind reverse proxy with termination and may improve site response.

Discover hostname:
- issue command

 hostnamectl

or

 hostname

Set or change hostname:
- issue command

hostnamectl set-hostname NEW-HOSTNAME

Set FQDN on instance behind reverse proxy with termination:
- edit /etc/hosts in vm or container using your favourite editor as root $ sudo nano /etc/hosts and add second line replacing <your.reverse.proxy.ip> <your.domain.xyz> and <hostname> with your own domain name and hostname:

127.0.0.1       localhost
<your.reverse.proxy.ip>   <your.domain.xyz>   <hostname>

## The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

your issue sounds like some sort of DNS issue, its always DNS
do you have some sort of local DNS like Pihole running in the local network? if so, you should tell the local DNS about your Nextcloud instance. Hosts and FQDN for Nextcloud snap · nextcloud-snap/nextcloud-snap Wiki · GitHub

scubamuc · December 9, 2025, 7:54am

one more question… is that the download/upload speed in the browser or Nextcloud Client?

Andrea_Tagini · December 10, 2025, 11:02pm

@scubamuc

Hi,

Thank you for your help and for the time that you’re using for me!

yes, Nginx is running on the same host as the snap & Nextcloud.

I used the local IP address instead of the localhost ip, as shown below, but nothing changed, I’m like 60/70 mbps of speed (down&up), on the same network and from outside my home network.

proxy_pass http://192.168.1.128:8400;

I set up the FQDN behind reverse proxy like you told me to do, I attach my /etc/hosts file down below. Using the configuration with the local IP inside the Nginx config file nothing changed on performance side.

127.0.0.1 localhost
127.0.1.1 server-tagini

192.168.1.128 cloud.mydomain.it server-tagini

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

I had PiHole running on the same server in a container, but I had the same performance problems before & after PiHole, but now I’m not using PiHole anymore. Now I’m using just the DNS from my provider.

All the tests that I’m performing are made with both of the those, with nextcloud client and with the browser (Google Chrome).

scubamuc · December 11, 2025, 6:48am

my pleasure

well done, good job

its clear Pihole is not the cause then… you should keep using Pihole, its a great piece of software!

well, you’ve done everything by the book, I’m out of ideas but be patient, there are some really clued up folks here in the forum who will certainly help…

Andrea_Tagini · December 11, 2025, 5:54pm

Hi,

thank you so much for your help, I hope someone will help me to fix this problem

I’ll reconsider PiHole

Have a good evening!

jtr · December 11, 2025, 8:54pm

Is the outward facing IP address of your reverse proxy on a different subnet?

What I’m getting at is the data path different when you go via the reverse proxy?

Andrea_Tagini · December 11, 2025, 9:10pm

Hi @jtr ,

no, everything is the same subnet, 192.168.1.0/24

jtr · December 14, 2025, 10:31pm

Even the public facing side of your Nginx proxy?

Andrea_Tagini · December 24, 2025, 10:22pm

Hi guys,

Thank you so much for your help.

I solved the problem switching to NPM (Nginx Proxy Manger), instead of using “normal” Nginx.

Merry Christmas to everyone!
