Issue with our ADFS server- Urgent

    Question

  • Hello,

    The issue we are facing with our ADFS environment currently is that some times our ADFS proxy servers fails to communicate with ADFS server and hence rejects the incoming requests by timeout.

    Our environment:

    Ver - ADFS 3.0, 2 ADFS proxy servers, 3 ADFS servers. and 2 hardware load balancing, one before proxy servers and another between proxy and ADFS. Total no of users: Around 10000 users.

    Server config: 8Vcpu, 16GB ram. enough disk space, on both ADFS and proxy servers.

    Please let me know if any other questions.

    error ID - Event 222, AD FS

    Event ID 222
    The federation server proxy was unable to complete a request to the Federation Service.

    The federation server proxy timed out while it was trying to reach the federation server. This might mean that the Federation Service is currently unavailable.

    Verify that the AD FS 2.0 Windows service is running on the remote federation server computer, and that the remote federation server is reachable.

    Event 230 AD FS.

    The Federation Service on the federation server proxy has detected congestion, caused by high latency response times. The load might be above the Federation Service operating capacity, or there might be network connectivity issues. Request throttling has been enforced to limit the number of concurrent requests to the following size: 64

    -With Thanks,

    Saravana
