@hquaemaxima ,

Thank you for posting in Zoom Developer Forum – I’m happy to help here. To start, can you share if you were seeing any error messages when trying to join the meeting with Andriod and IOS SDK?

We create a meeting by JWT in the backend , the IOS app gets the join link and tries to join by meeting id and password
With the IOS SDK (latest version), you can see the IOS in the attachments above.
JWT backend - Use the secret key in our application (JWT)
IOS SDK - Use the SDK key in our app (HQA)
Below is the response
Case 1, then 4, then 7
without any error msg

Below is the backend - JWT meeting creation code

string token = GenerateToken();

            if (string.IsNullOrEmpty(token))
                throw new Exception("no auth");
            meeting.timezone = _configuration.GetValue<string>("Zoom:Timezone");

            string user_id =string.IsNullOrEmpty(userZoomId)? _configuration.GetValue<string>("Zoom:user:Id"): userZoomId;
            meeting.schedule_for =string.IsNullOrEmpty(userZoomId)? _configuration.GetValue<string>("Zoom:user:email") : meeting.schedule_for;
            string url = _APIs_Base_Url+ "users/"+user_id+"/meetings";
            //var converter = new StringEnumConverter();
            string body = JsonConvert.SerializeObject(meeting);
            byte[] buffer = Encoding.UTF8.GetBytes(body);

            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(url, UriKind.RelativeOrAbsolute));
            request.Method = "POST";
            request.ContentType = "application/json";
            request.Accept = "application/json";
            request.Headers["Authorization"] = "Bearer " + token;
            Stream PostData = request.GetRequestStream();
            PostData.Write(buffer, 0, buffer.Length);

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                Stream dataStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream);
                string string_response = reader.ReadToEnd();
                results = JsonConvert.DeserializeObject<CreateZoomMeetingResults>(string_response);

Thank you for providing those details! It is strange that you are able to authorize the SDK when in development but not production. Is there anything different from your developer environment? I’ve seen developers encounter such behavior when the clock on the machine is not synced. Can you share if there is any difference between the production clock? In the meantime, here is a troubleshooting guide you can reference :

Now the development environment has the same issue , it was working totally fine, but for now we can’t join .

Please advise what we should do, should we change in the settings, or move to grant the user in the mobile SDK token? The important point is that we need to join the user from the mobile phone as a guest ( by meeting Id and password ), so why does he need the token?

Thanks for the update, @hquaemaxima! The first thing I’d recommended is isolating where the problem is happening. You can do so by using the Zoom Meeting SDK Auth Endpoint sample to generate SDK JWT, then manually entering the token to join the meeting. This will help identify if the problem you are seeing results from how you are generating the token. I’ve shared the Zoom Meeting SDK Auth Endpoint sample app below for you to look over.

That aside, can you please share the following information :

  1. Can you share if you reviewed the SDK JWT troubleshooting steps outlined here.?

  2. Can you clarify the role type of the user joining the meeting from your mobile phone?

  3. Do you happen to know how the meeting setting is configured? Do you have registration enabled?
