I installed gitea 1.7.6 on Unbuntu 18.04 LTS with Apache 2.4.26 and Mysql.  
When app.ini configuration had `PROTOCOL = https` I an into Problems with letsencrypt  
`[E] Failed to load https cert file localhost:3000: open /etc/letsencrypt/live/git.arbyte.net/fullchain.pem: permission denied`

So I went for the solution provided [here](https://github.com/go-gitea/gitea/issues/4537) and set `PROTOCOL = http`.  
This is my configuration in `app.ini`:

```auto
[server]
PROTOCOL = http
ROOT_URL = https://my.domain.tld/
SSH_DOMAIN = my.domain.tld
DOMAIN = my.domain.tld
HTTP_PORT = 3000
HTTP_ADDR = localhost
DISABLE_SSH = false
SSH_PORT = 22
LFS_START_SERVER = true
LFS_CONTENT_PATH = /var/lib/gitea/LFS

```

Service is running now but doing so gives me this in the Browser:

# Proxy Error

The proxy server received an invalid response from an upstream server.  
The proxy server could not handle the request _[GET /](https://my.domain.tld/)_ .

Reason: **Error reading from remote server**

and apache’s error.log:

```auto
[proxy_http:error] [pid 28572] (103)Software caused connection abort: [client 84.113.179.56:51972] AH01102: error reading status line from remote server localhost:3000

```

Any Ideas?

```auto
