LetsEncrypt toggle disabled after upgrading nethvoice-proxy with old core/traefik

[stephdl]

Bug description

When upgrading nethvoice-proxy from 1.5.0 to 1.5.1-testing.5, and upgrading from old versions of core (3.8.1) and traefik (3.2.1), the LetsEncrypt toggle is not automatically enabled in the nethvoice-proxy module settings, even if a valid LetsEncrypt certificate exists for the configured FQDN. The related configuration file (set-certificate-nethvoice-proxy1.yml) is also not created, causing the module to not use the existing certificate to enable the Toggle unless the settings form is saved a second time with the LetsEncrypt toggle enabled. This regression does not occur when upgrading from more recent/updated versions.

This behavior may potentially affect all modules that require a set-certificate file for their configuration, not just nethvoice-proxy.

Steps to reproduce

• Install old version of core and traefik:

  curl https://raw.githubusercontent.com/NethServer/ns8-core/main/core/install.sh > install.sh
  bash install.sh ghcr.io/nethserver/traefik:3.2.1 ghcr.io/nethserver/core:3.8.1
  

• Create a LetsEncrypt certificate for the FQDN of the server
• Install nethvoice-proxy stable (1.5.0), set the FQDN to the FQDN of the server
• Upgrade core and traefik to the latest stable release
• Upgrade nethvoice-proxy to the latest testing version (1.5.1-testing.5)
• Open the nethvoice-proxy module settings

Expected behavior

• The 'LetsEncrypt' toggle should be enabled if the FQDN used by nethvoice-proxy has a valid LetsEncrypt certificate.
• All required configuration files (e.g., set-certificate-nethvoice-proxy1.yml) should be present after upgrade.

Actual behavior

• The LetsEncrypt toggle is OFF (should be ON inside the module settings).
• The configuration file set-certificate-nethvoice-proxy1.yml is missing after the upgrade:

  # tree /home/traefik1/.config/state/configs/
  /home/traefik1/.config/state/configs/
  ├── _api.yml
  ├── cluster-admin.yml
  ├── _default_cert.yml
  └── _http2https.yml
  

• If the module settings form is saved a second time with the LetsEncrypt toggle ON, the missing file appears:

  # tree /home/traefik1/.config/state/configs/
  /home/traefik1/.config/state/configs/
  ├── _api.yml
  ├── cluster-admin.yml
  ├── _default_cert.yml
  ├── _http2https.yml
  └── set-certificate-nethvoice-proxy1.yml
  

• With the latest stable version, the bug is NOT reproducible – only when upgrading from this old core/traefik version scenario.

Components

• nethvoice-proxy: 1.5.1-testing.5 (upgrade from 1.5.0)
• traefik: ghcr.io/nethserver/traefik:3.2.1 → latest
• core: ghcr.io/nethserver/core:3.8.1 → latest

Possible fixes

• Easy fix: Save the form again with the LetsEncrypt toggle enabled after the upgrade.
• Complicated fix: Patch traefik to ensure the set-certificate-nethvoice-proxy1.yml is written during upgrade.
