Host Anvil Runtime app on SSL domain

I am trying to run Anvil Runtime on a Namecheap VPS using Webuzo panel using the command…
anvil-app-server --app /apps/Manage_Crucis_Tours_App --port 30000 --origin https://develop.crucis.tours --disable-tls

Have to use port 30000 instead of 3030 because of the Webuzo panel application configuration requirements.
Have used parameter --disable-tls so that it doesn’t trigger installation of Traefik SSL certificate which is failing with the error

WARN[2025-04-02T10:14:01Z] No domain found in rule PathPrefix(`/`), the TLS options applied for this router will depend on the hostSNI of each request  entryPointName=https routerName=https-route@file
ERRO[2025-04-02T10:14:07Z] Unable to obtain ACME certificate for domains "develop.crucis.tours" : unable to generate a certificate for the domains [develop.crucis.tours]: error: one or more domains had a problem:
[develop.crucis.tours] acme: error: 400 :: urn:ietf:params:acme:error:tls :: 203.161.41.212: remote error: tls: no application protocol  providerName=letsEncrypt.acme

Therefore, using the Let’s Encrypt SSL certificate installed on domain by Webuzo.

However, when I access the app on https://develop.crucis.tours I get the error…
AppOfflineError: Connection to server failed (error)
