Share Site tunnel silently disconnects after several hours while app still shows it as active

[rakibatomnixima]

Description

The Share Site tunnel appears to drop on the server side after running for an extended period (roughly 4–6 hours), but the Blaze app's UI continues to show the tunnel as active. Visiting the public *.blze.site URL during this state returns:

Tunnel Not Active
The site <subdomain>.blze.site is not currently shared.
Powered by Blaze

Stopping the tunnel from the app and starting it again restores the connection immediately.

Steps to reproduce

1. Start a local WordPress site in Blaze.
2. Enable Share Site with a custom subdomain.
3. Confirm the public *.blze.site URL loads the site correctly.
4. Leave the tunnel running for ~4–6 hours (machine awake, network stable).
5. Revisit the public URL.

Expected behavior

• The tunnel stays connected for as long as the app reports it as active, or
• If the connection is lost, the app surfaces the disconnected state and/or auto-reconnects.

Actual behavior

• Public URL shows the "Tunnel Not Active" page.
• Blaze app still displays the tunnel as on (no error, no reconnect).
• Manually toggling Share Site off and on restores it.

Environment

• Blaze version: v0.5.6
• macOS version: 26.3.1
• Mac: Apple Silicon (M1)
