-## Permanently Enable Mycelium
 
-It is possible to permenently enable Mycelium on your client.
+## Troubleshooting
 
-For Linux, we use systemd to manage the mycelium daemon in `/storage/`. Here's an example:
+### Root Access
+
+You might need to run Mycelium as root. Some error messages could be something like: `Error: NixError(EPERM)`.
+
+### Enable IPv6 at the OS Level
+
+You need to enable IPv6 at the OS level. Some error messages could be something like: `Permission denied (os error 13)`.
+
+- Check if IPv66 is enabled
+  - If disabled, output is 1, if enabled, output is 0
+  ```
+  sysctl net.ipv6.conf.all.disable_ipv6
+  ```
+- Enable IPv6
+  ```
+  sudo sysctl net.ipv6.conf.all.disable_ipv6=0
+  ```
+
+Here's some commands to troubleshoot IPv6:

+### VPN Can Block Mycelium
+
+You might need to disconnect your VPN when using Mycelium.
+
+### Add Peers
+
+It can help to connect to other peers. Check the Mycelium repository for [peers](https://github.com/threefoldtech/mycelium?tab=readme-ov-file#hosted-public-nodes).
