     - You should add a CORS Policy on your bucket, check the issue [#193](https://github.com/Joxit/docker-registry-ui/issues/193).
 -   Why my docker registry server is returning an error `pagination number invalid` ?
     - Since docker registry server 2.8.2 there is default limit of 1000 images in catalog. If you need more images update the configuration `REGISTRY_CATALOG_MAXENTRIES` with your max value and check the issue [#306](https://github.com/Joxit/docker-registry-ui/issues/306).
+-   I'm using `NGINX_PROXY_PASS_URL`, my registry server has been recreated and the UI cannot connect with the message `[error] 176#176: *2 connect() failed (111: Connection refused) while connecting to upstream`, what can I do?
+    - Nginx get the IP of all addresses only once at runtime, since your container has been recreated, its IP changed too. To prevent this kind of issue, you may use the option `NGINX_RESOLVER` and set to `127.0.0.11`.

 - `NGINX_PROXY_HEADER_*`: Update the default Nginx configuration and **set custom headers** for your backend docker registry via environment variable and file (`/etc/nginx/.env`). Only when `NGINX_PROXY_PASS_URL` is used (see [#89](https://github.com/Joxit/docker-registry-ui/pull/89)). Since 1.2.3
 - `NGINX_PROXY_PASS_HEADER_*`: Update the default Nginx configuration and **forward custom headers** to your backend docker registry via environment variable and file (`/etc/nginx/.env`). Only when `NGINX_PROXY_PASS_URL` is used (see [#206](https://github.com/Joxit/docker-registry-ui/issues/206)). Since 2.1.0
 - `NGINX_LISTEN_PORT`: Listen on a port other than 80, you can also change the default user and set to nginx `--user nginx` (see [#224](https://github.com/Joxit/docker-registry-ui/issues/224) and [#234](https://github.com/Joxit/docker-registry-ui/pull/234)). (default: `80` when the user is root, `8080` otherwise). Since 2.2.0
+- `NGINX_RESOLVER`: Add [`resolver`](http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver) directive to the nginx configuration for dynamic dns resolving. The value when you are using a docker network is `127.0.0.11`, you can set a custom DNS server too with a valid time. This is not needed when you are using kubernetes. (see [#333](https://github.com/Joxit/docker-registry-ui/issues/333) and [#339](https://github.com/Joxit/docker-registry-ui/issues/339)). (default: ``). Since 2.5.5

 - `READ_ONLY_REGISTRIES`: Deactivate dialog for remove and add new registries, available only when `SINGLE_REGISTRY=false` (see [#219](https://github.com/Joxit/docker-registry-ui/pull/219)). (default: `false`). Since 2.1.0
 - `SHOW_CATALOG_NB_TAGS`: Show number of tags per images on catalog page and hide images with 0 tags. This will produce + nb images requests, **not recommended on large registries** (see [#161](https://github.com/Joxit/docker-registry-ui/issues/161) and [#239](https://github.com/Joxit/docker-registry-ui/pull/239)).
