WorkCast Studio Whitelisting Access
The WorkCast Studio allows you to present and see a range of communication pods to interact with other presenters and attendees.
| Category | Addresses | Ports |
| Studio Page | *.workcast.com | TCP: 443 |
| d2vob9ylg6o903.cloudfront.net | TCP: 443 | |
| d2uwbgdpur2zq9.cloudfront.net | TCP: 443 | |
| Interactive & Cloud Slides | *.workcast-interactive.com | TCP: 443, 80 UDP: 10000 (Ideally) 443 (Minimum) |
| *.eventassist.workcast.com | TCP: 443 | |
| Realtime Communication | realtime.ably.io | TCP: 443 for secure WebSocket (WSS) connections |
| *.ably-realtime.com | TCP: 443 for HTTPS or secure WebSocket (WSS) connections | |
| Realtime Communication & Schedule Replay | *.gp.workcast.com |
TCP: 443 |
If you have chosen the Live Stream presentation type there will be an onsite AV team and they will be pushing their content via a vision mixer to the WorkCast platform via onsite streaming technology. The venue will need to review the below information prior to the on day live stream.
|
Stream Format |
Firewall TCP Ports (inbound and outbound) |
Comments |
|
RTMP (real-time messaging protocol) |
All of the following: |
NOTE: RTMP traffic must also be allowed through the firewall. |
|
HLS (HTTP live streaming) |
80 |
|
|
Mpeg-dash (dynamic adaptive streaming over HTTP) |
80 |
Proxy Server/VPN
Not using a proxy server/VPN is recommended
Why?
-
VPNs are typically not designed or configured to support real-time media.
-
Connectivity to WorkCast might not be efficient due to hair-pinning traffic through a VPN device.
When it comes to WorkCast traffic over proxies, we recommend bypassing proxies. Proxies don't make WorkCast Studio more secure because the traffic is already encrypted.
And having a proxy can cause issues. Performance-related problems can be introduced to the environment through latency and packet loss. Issues such as these will result in a negative experience in such WorkCast Studio scenarios as audio and video, where real-time streams are essential.
Some organisations have no option to bypass a proxy for WorkCast traffic. If that's the case for you, the problems mentioned above need to be kept in mind.
We also strongly recommends:
- Using direct UDP based routing
- Allowing UDP traffic
For attendees and presenters there are no WorkCast downloads or plugins required.
Hardware & Software Requirements
Processor, RAM & CPU Bit Requirements
| Component | Minimum | Recommended |
|---|---|---|
| Processor | Dual-core 2Ghz or higher | Quad-core 2.5Ghz or higher |
| RAM | 4 GB | 16 GB |
| CPU bit | 32/64 | 64 |
Notes:
- Dual and single-core laptops have a reduced frame rate when screen sharing (around 5 frames per second). For optimum screen-sharing performance on laptops, we recommend a quad-core processor or higher.

If the current version of Chrome is 111, WorkCast supports versions 109, 110, and 111. When a new version (112) is released, support shifts to 110, 111, and 112.
Connection & Bandwidth Requirements
For an optimal experience, the following internet speeds are recommended:
-
Minimum recommended speeds:
- Download: 2 Mbps
- Upload: 2.6 Mbps
