After successfully installing the SSL certificate for Zimbra Chat, I can access it from both desktop and mobile apps. If you have not installed Zimbra Chat yet, please follow this guide: “How to Integrate Zulip (Zimbra Chat) with Zimbra Mail Server”
Go to the Zulip apps download page: https://zulip.com/apps/
After downloading the app, configure it to connect to Zimbra Chat.
Zulip Desktop:
Open Zulip desktop apps. Insert Zimbra Chat Server URL like below
Insert username and Password
Now you can use Zulip desktop apps for Chit-chat 🙂
Mobile Apps:
Open Zulip mobile apps. Insert Zimbra Chat Server URL
Insert username and password
Now you can use Zulip mobile apps for Chit-chat 🙂
Good Luck 🙂
