# Website FAQ
|
|
|
|
## Website Inaccessible
|
|
|
|
1. Check if the domain is resolved to the server IP
|
|
2. Check if the firewall has allowed ports 80/443
|
|
3. Check if Nginx is running: **Apps** -> **Nginx** -> **Manage**
|
|
4. View Nginx error logs
|
|
|
|
## 403 Forbidden
|
|
|
|
Usually a permission issue:
|
|
|
|
```shell
|
|
# Fix website directory permissions
|
|
chown -R www:www /opt/ace/sites/website-name/public
|
|
chmod -R 755 /opt/ace/sites/website-name/public
|
|
```
|
|
|
|
## 502 Bad Gateway
|
|
|
|
For PHP websites with 502, check if PHP is running:
|
|
|
|
1. **Apps** -> **Runtimes** -> **PHP** -> **Manage**
|
|
2. Confirm PHP version matches website configuration
|
|
3. View PHP error logs
|
|
|
|
For reverse proxy websites with 502, check if the backend service is running.
|
|
|
|
## Rewrite Rules Not Working
|
|
|
|
1. Confirm the correct preset is selected or rules are filled in the **Rewrite** tab
|
|
2. Nginx will automatically reload after clicking **Save**
|
|
3. Clear browser cache and test
|
|
|
|
## Configure QUIC (HTTP/3)
|
|
|
|
The panel supports QUIC, but does not add the `Alt-Svc` header by default. Add in custom configuration:
|
|
|
|
```nginx
|
|
add_header Alt-Svc 'h3=":$server_port"; ma=2592000';
|
|
```
|
|
|
|
Ensure the server security group/firewall allows UDP port 443.
|
|
|
|
## Enable TLSv1/TLSv1.1
|
|
|
|
OpenSSL 3.x disables old protocols by default. If you must use them, modify the cipher suite in **HTTPS** settings:
|
|
|
|
```nginx
|
|
ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:AES128-SHA:AES256-SHA:DES-CBC3-SHA:@SECLEVEL=0;
|
|
```
|
|
|
|
## Enable IPv6
|
|
|
|
Add listening addresses in **Domains and Listening**: `[::]:80` and `[::]:443`.
|
|
|
|
## CDN Origin and HTTPS
|
|
|
|
| CDN Origin Protocol | Website HTTPS Configuration |
|
|
|---------------------|--------------------------------------------------------|
|
|
| HTTP | Not required |
|
|
| HTTPS | Must be enabled |
|
|
| Follow Protocol | Must be enabled, and HTTP redirect must not be enabled |
|
|
|
|
## Upload File Size Limit
|
|
|
|
Default limit is 100MB. Modify PHP configuration:
|
|
|
|
1. **Apps** -> **Runtimes** -> **PHP** -> **Manage** -> **Main Configuration**
|
|
2. Modify `upload_max_filesize` and `post_max_size`
|
|
3. Restart PHP after saving
|
|
|
|
## SSL Certificate Application Failed
|
|
|
|
1. Confirm the domain is resolved to the server
|
|
2. Confirm port 80 is accessible (required for Let's Encrypt verification)
|
|
3. Check if Let's Encrypt rate limit is exceeded
|
|
4. Try using DNS verification method
|
|
5. Switch to another certificate provider
