I have the following snippet where I’m trying to take everything after my slash and send it to a remote server. Is there anything I’m doing obviously wrong here?

location ~ ^/(http[s]?:/.*) {
                proxy_pass $1;  # Ensures correct URL formation
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_read_timeout 600s;
                proxy_connect_timeout 600s;
                proxy_send_timeout 600s;
                proxy_ssl_verify off;
            }
