In this article we will go over the connectivity requirements of CareAR needed by the network. If the CareAR app does not seem to connect when you log in, you’ll want to confirm that you have no network issues. If your connection is good but still does not seem to connect you may need to provide your IT team managing the network with this guide. By missing any of the following network port connection requirements might lead to a poor or problematic experience.
CareAR Authentication Firewall Requirements
These are the connections outside of media traffic that are necessary for the optimal CareAR experience. These remain the same regardless of Proxy, joining application, and Media Geofencing configuration.
| Purpose | Domain | Port(s) |
| CareAR client | us-central1-carear-v0.cloudfunctions.net | 443 TCP |
| Auth | firestore.googleapis.com | 443 TCP |
| Auth | carear-v0.firebaseapp.com | 443 TCP |
| Auth | apiv2.carear.app | 443 TCP |
| Realtime database | carear-v0.firebaseio.com | 443 TCP |
| Storage | carear-v0.appspot.com | 443 TCP |
| Storage | firebasestorage.googleapis.com | 443 TCP |
| CareAR Web Portal | carear.app/* | 443 TCP |
| Session invitation | carear.page.link/* | 443 TCP |
| Session invitation | carearjoin.page.link/* | 443 TCP |
| User Web Portal | carear.app/#/user | 443 TCP |
| Admin Web Portal | carear.app/#/admin | 443 TCP |
| Network Health Check | 8.8.8.8 (Google Public DNS) | ICMP |
CareAR Media Firewall Requirements (Installed Application)
When a CareAR session is initiated, all users need to establish connectivity to transmit audio between participants, the camera of the collaborator, and the annotations placed. To accomplish this portion of the session is handled with the following media connections.
| Domain | Port Type | Ports |
| *.agora.io | TCP | 53, 80, 443, 7000 - 10000, 30000 - 31000, 51000 - 52000 |
| UDP | 53, 4000-6000, 8000 - 10000 |
When using Media Geofencing your connection will utilize servers within the selected region using the *.agora.io domain.
Need to refine Firewall controls further?
In some situations the firewall administrator may prefer a more restrictive firewall rule set over ideal connectivity. This is accomplishable through the media proxy service (configurable on the /admin page). To view these more restrictive firewall rules please visit our media proxy firewall guide available here: Media Proxy Firewall Configurations
CareAR System Emails
CareAR utilizes email to process certain user-initiated actions. These emails are to facilitate session invitations, new user account creation, and password resets. CareAR utilizes the following email addresses to serve these requests:
|
Email notifications |
If your email system has email filtering you may need to whitelist these addresses to assure emails do not move to spam or junk.
The CareAR System emails are generated during the following events:
|
Trigger Operation |
Sender Email Address |
Subject |

| Session Invite | service@carear.com | CareAR call Invite |
| Captcha | service@carear.com | CareAR Verification Code |
| Low Balance Notification | service@carear.com | CareAR-Low Balance |
Sender IP Address
Emails that are coming from the sender service@carear.com are configured to inbound from 159.183.166.109.
Bandwidth Requirements
CareAR sessions require at least 500 Kbps to maintain connection. Having more bandwidth than this can allow for an even better experience. If you would like to see data consumption over a period of time please visit our article here: Data Consumption Usage
