The Settings page controls platform-wide basics: your public URL + SSL, automatic updates, email notifications (SMTP), timezone, and access allow-list. Changes here affect the whole panel, not just your user.

Who can change this

Requires both view_settings_page and change_settings permissions. Without the latter, fields are read-only and the SMTP test button is disabled.

Site domain & SSL

• Site domain — set the hostname the panel should answer to (e.g. backup.yourdomain.com). Use only the host name (no http://, no slashes or ports).
• DNS prerequisite — create an A record pointing that host to this server’s public IP before enabling SSL.
• Let’s Encrypt SSL — when checked, Synconix configures Nginx and requests a certificate. If DNS doesn’t resolve to this server, issuance will fail. Ensure ports 80/443 are reachable.
• The title bar and API/plugin callbacks rely on this URL, so keep it accurate.

Auto updates

• When enabled, the panel tracks your chosen tier and installs new builds automatically.
• Safe to turn off for change-controlled environments; you can still update manually later.

Backup notifications (SMTP)

Configure the sender used for all alert emails (run started/completed, warnings, errors, time-running notices).
• From email — the visible sender address (often the same as your SMTP username).
• SMTP Hostname/IP — e.g. mail.example.com.
• Username / Password — mailbox credentials. Password is write-only: leave it blank to keep the current one.
• Port — choose a matching security: 25/26 = none, 465 = SSL, 587 = TLS.
• SMTP Test! — sends a message to the “From email”. On failure, a debug window shows the full SMTP handshake so you can spot auth or TLS issues.

Timezone

Sets the server and PHP timezone used across the UI (logs, schedules, activity). If timestamps look off, confirm this first.

Security (IP allow-list)

IP Addresses allowed to connect to this Panel — add one or more IPv4 addresses. When set, only listed IPs can access the UI (CLI and certain internal endpoints are exempt).
• Use comma-separated values in the input (the field accepts tags).
• Locked yourself out? SSH into the host and clear the allow-list file, then reload the page.

Saving changes

• Clicking Save changes updates application settings immediately. SSL changes may briefly reload the web server. If you enabled SSL and the page doesn’t reload under https://, re-check the DNS record and try again.

Troubleshooting

• SSL won’t issue: confirm the hostname resolves to this server, firewalls allow 80/443, and you didn’t include protocol or path in the domain field.
• SMTP test fails: verify host/port/security trio, credentials, and any firewall/relay restrictions. The debug modal shows the exact error from the mail server.
• Emails not received: check spam, SPF/DKIM/DMARC on your domain, and that “From email” matches an allowed sender on your SMTP host.
• Timestamps off: set the correct timezone and reload the browser tab.

Good practices

• Use a dedicated mailbox (e.g., synconix-alerts@domain) and restrict its credentials.
• Keep the allow-list small; add your office VPN egress IP if your ISP IP changes.
• Document who can toggle Auto updates and SSL in your team runbook.
