rodan prod gives empty pages sometimes

everything seems fine on the server, tho

from instance that belongs to rodan prod and also from prod edge:
```
HTTP/1.1 200 OK
Server: nginx
Date: Fri, 09 May 2025 14:08:57 GMT
Content-Type: text/html
Content-Length: 65608

```
and from local:
```
HTTP/1.1 200 OK
Server: nginx

```

It is a very strange error. I checked the NGINX container, including Docker volume mount, file permission etc. Everything looks fine. Also on the server, the memory usage is also ok. Docker status is fine, too.
I restared docker but it does not solve the issue.

From the browser:
```
rodan_client.min.js:1
Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH
```
