I just finished the upgrade to Electric Eel and migration of apps to Docker. Everything went well, except for my Nextcloud instance. It’s configured to use a subdomain and worked before the migration, but now it appears to refuse any connections. I have already restarted the app and reapplied the settings.
The subdomain is managed through Cloudflare (cloudflared). I have other services using the same system, all of which work after the migration.
Please suggest things to check!
