Expose Nextcloud

Access your Nextcloud instance from anywhere through SeaWise.

Prerequisites

• Nextcloud running on your home server

• SeaWise client installed and paired

Step 1: Find Nextcloud's Port

Common Nextcloud ports:

• 443 (HTTPS) or 80 (HTTP) for native installs

• 8080 or 8443 for Docker setups

Check your setup:

docker ps | grep nextcloud

Step 2: Add Nextcloud to SeaWise

In the client web UI at http://your-server-ip:8082:

1. Click Add Service

2. Name: Nextcloud

3. Host: localhost

4. Port: your Nextcloud port (e.g., 8080)

5. Click Add

Step 3: Configure Nextcloud

Add Trusted Domain

Nextcloud only responds to requests from configured trusted domains. Add your SeaWise subdomain:

Edit config/config.php:

'trusted_domains' =>
array (
  0 => 'localhost',
  1 => 'your-subdomain.seawise.dev',
),

Or via Docker environment variable:

NEXTCLOUD_TRUSTED_DOMAINS=localhost your-subdomain.seawise.dev

Set Overwrite URL

Tell Nextcloud its public URL:

'overwrite.cli.url' => 'https://your-subdomain.seawise.dev',
'overwriteprotocol' => 'https',

Trusted Proxies

Add the SeaWise client as a trusted proxy:

'trusted_proxies' =>
array (
  0 => '127.0.0.1',
  1 => '172.16.0.0/12',
),

Restart Nextcloud after making changes.

Step 4: Access Nextcloud

Visit:

https://your-subdomain.seawise.dev

Tips

• Desktop and mobile sync: The Nextcloud desktop and mobile clients work with SeaWise — enter your SeaWise URL as the server address

• Large file uploads: Upload speed depends on your home internet's upload bandwidth

• Collabora/OnlyOffice: Document editing through Nextcloud works, but may be slow on low-bandwidth connections

Troubleshooting

"Access through untrusted domain"

Add your SeaWise subdomain to the trusted_domains array in config.php. See Step 3 above.

File sync not working

Make sure the overwrite.cli.url is set correctly and overwriteprotocol is set to https.
