How can I fix it if txt, sh, md files aren't shown in bitbucket?

My nginx proxy return 403 forbidden error.

Nginx proxy config

location ~ / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://10.0.0.3:7990;
client_max_body_size 300M;
}
