To find out which data center you are using, look in your system data under "Datacenter".
| Datacenter | DNS Entries |
|---|---|
| Germany – Magdeburg | otc-eu-de-turn.oneclick.services |
| Germany - Central | hetzner-fra-turn.oneclick.services |
| Switzerland – Zurich | gc-europe-west6-turn.oneclick.services |
| USA East Coast – Ashburn | hetzner-useast-turn.oneclick.services |
If you can only whitelist IP addresses, you can find the appropriate IP address in this article.
If you cannot make these settings yourself, please contact your administrator.
Please proceed as the following:
- Check with your administrator whether "UDP Higher Ports" are allowed in your firewall.
- Include the displayed DNS name in the whitelist of your firewall and unblock ports 443 UDP and TCP. These will ensure that the streaming protocol via webRTC will work.
We recommend activating WebRTC; to check whether WebRTC is working, go to the Webcasts page.
