How to modify to work with HAProxy new load balance/

To configure HAProxy to work as a load balancer for your Nextcloud instance, you'll need to update your HAProxy configuration file to properly route traffic to your Nextcloud instance running on hc4Noble.yushei.net:45101.

Here's a modified version of your haproxy.cfg file with the necessary changes:

Frontend Configuration: You'll need to add a new frontend section to handle HTTP traffic on port 80 and HTTPS traffic on port 443, and route it to the backend. Backend Configuration: Add a backend section to handle the Nextcloud server, ensuring it points to the correct internal IP and port. Here’s the updated haproxy.cfg:

backend nextcloud_backend server nextcloud_server hc4Noble.yushei.net:45101 Explanation: Frontend Configuration:

frontend http_80_front: Binds to port 80 and redirects all HTTP traffic to HTTPS. frontend https_443_front: Binds to port 443 and handles HTTPS traffic, using the SSL certificate located at /etc/letsencrypt/live/munetaka.me/haproxy.pem. Backend Configuration:

backend nextcloud_backend: Defines a backend for the Nextcloud server, pointing to the internal server address hc4Noble.yushei.net:45101. Nextcloud Configuration: Update the Nextcloud configuration to reflect the use of HAProxy. Ensure that the trusted_proxies and overwrite.cli.url settings are correctly set. Here's the relevant section of your config.php:
