Brella

If Brella works on your phone's mobile data but not on your company network, the network blocks part of the app. Give this list to your IT team.

Allow these on port 443 (HTTPS and secure WebSocket):

<code>https://*.brella.io</code> — the web app (<code>next.brella.io</code>), the API (<code>api.brella.io</code>), images (<code>brella.io/cdn-cgi/image</code>), uploaded images and files (for example <code>brella-assets.brella.io</code>) and event web addresses. Branded event apps also use an address ending in <code>.brella.io</code>.

<code>wss://*.brella.io</code> — the live connection for chat, meeting updates and announcements. It goes to <code>api.brella.io</code>.

<code>https://hot-updater.brella.workers.dev</code> — mobile app updates.

- <code>https://*.brella.io</code> — the web app (<code>next.brella.io</code>), the API (<code>api.brella.io</code>), images (<code>brella.io/cdn-cgi/image</code>), uploaded images and files (for example <code>brella-assets.brella.io</code>) and event web addresses. Branded event apps also use an address ending in <code>.brella.io</code>.
 
- <code>wss://*.brella.io</code> — the live connection for chat, meeting updates and announcements. It goes to <code>api.brella.io</code>.
 
- <code>https://hot-updater.brella.workers.dev</code> — mobile app updates.

Brella does not use Sendbird or <code>magic.link</code>. Remove both from old allow lists.

Sign-in code step: <code>https://*.hcaptcha.com</code> (the captcha check before the code email is sent). The web app loads <code>js.hcaptcha.com</code>.

Push notifications: <code>https://*.onesignal.com</code>. The web app loads the OneSignal SDK from <code>cdn.onesignal.com</code>.

Video calls (1:1 meetings, group meetings and breakout rooms): <code>https://*.whereby.com</code>. Rooms are on <code>brella.whereby.com</code>. Whereby's own network requirements for audio and video traffic also apply.

Live streams and session videos: the video provider the organizer uses (for example YouTube, Vimeo or Zoom). The player is loaded from the provider's address.

Videos uploaded to Brella (pitch reels): <code>*.cloudflarestream.com</code> and <code>*.videodelivery.net</code>.

Support chat (only when the event has it): <code>https://*.intercom.io</code>, <code>wss://*.intercom.io</code>, <code>*.intercomcdn.com</code>, <code>*.intercomassets.com</code>.

Interactive maps (only when the event has one): <code>*.expofp.com</code>, <code>*.cartocdn.com</code>, <code>unpkg.com</code>, <code>*.jsdelivr.net</code>.

Error reporting: <code>*.ingest.us.sentry.io</code>. Blocking it does not break the app.

Brella's emails, including sign-in codes, come from <code>noreply@brella.io</code>. If the organizer sends from their own domain, event emails come from that domain; in a branded event app, sign-in codes can also come from it. Ask IT to allow <code>*@brella.io</code> and the organizer's domain.

In the web app, open Account &gt; Troubleshoot. The Browser check reports "Some services blocked" and names the service (Notifications, Support chat or Captcha) when a blocker or firewall stops it. The Internet connection check shows whether the server answers and whether the live connection works.

Ad blockers and privacy extensions block the same services. Pause them for the web app and reload.

{appName} in 60 seconds

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
