We appreciate you for posting here at the Roku Community, @Tomcat77!
No worries! We're here to find you the best resolution possible. Would you mind providing us with a photo of the error message prompted on your screen? What Roku streaming device are you having this issue with? In addition, have you tried to perform a system reboot on your network connection's router? If not, we highly suggest so.
Once we have a more precise grasp of the situation, we can recommend the appropriate next steps. We'll be looking forward to your update!
Kind regards,
Carly
