smba.trafficmanager.net REQUEST_SEND_ERROR problem

Hi,

I am developing a digital assistant. In the architecture there's a REST API server behind the Teams application. Both servers are located in same network. The problem I am facing that the request send error problem if response time taking long time (5 hours) from server side. Error log says getaddrinfo ENOTFOUND smba.trafficmanager.net but I am able to ping smba.trafficmanager.net on the system where teams application is running on. I do not face with same problem in short period of time responses

Please find error log below;

RestError: request to https://smba.trafficmanager.net/emea/...... failed, reason: getaddrinfo ENOTFOUND smba.trafficmanager.net

....
    at process.processTicksAndRejections (node:internal/process/task_queues:105:5) {
  code: 'REQUEST_SEND_ERROR',

.

.

.

Thank you for your support.

    Hi,

    I fixed the problem. The problem occurred because of high number of requests (every 1 sec) to smba.trafficmanager.net by calling statement below in the code, during REST API call period.

    await stepContext.context.sendActivity({ type: 'typing' });

    So, firewall thinks that it is an attack and blocks to send data to after a while. I recommend send this signal every 3 secs.

    Best regards,
