 If 1 or 2 did not work, ensure your Docker install is at least version 20.10.0, [refer to the official Docker docs for installation.](https://docs.docker.com/engine/install/debian/)
 
 #### Option 1
+
 Manually install an updated version of the library with dpkg.
 
-    ```bash
+```bash
-    wget http://ftp.us.debian.org/debian/pool/main/libs/libseccomp/libseccomp2_2.4.4-1~bpo10+1_armhf.deb

 #### Option 2

 Add the backports repo for DebianBuster. As seen [here](https://github.com/linuxserver/docker-jellyfin/issues/71#issuecomment-733621693).

+sudo apt install -t buster-backports libseccomp2

 #### Option 3
-Reinstall/update your OS to a version that still gets updates.
-    * Any distro based on DebianStretch does not seem to have this package available
-    * DebianBuster based distros can get the package trough backports, as outlined in point 2.

+## I want to reverse proxy a application which defaults to https with a selfsigned certificate {#strict-proxy}
+
+### Traefik {#strict-proxy-traefik}
+
+In this example we will configure a serverTransport rule we can apply to a service, as well as telling Traefik to use https on the backend for the service.
+
+Create a [ServerTransport](https://doc.traefik.io/traefik/routing/services/#serverstransport_1) in your dynamic Traefik configuration, we are calling ours `ignorecert`.
+
+```yml
+    http:
+    serversTransports:
+        ignorecert:
+            insecureSkipVerify: true
+```
+
+Then on our `foo` service we tell it to use this rule, as well as telling Traefik the backend is running on https.
+
+```yml
+    - traefik.http.services.foo.loadbalancer.serverstransport=ignorecert
+    - traefik.http.services.foo.loadbalancer.server.scheme=https
+```
