CRM 2016 v8.1 Web Secure Channel Failure

(0) ShareShare
ReportReport
Posted on by

I have a handful of users that we have Server-Side Synchronization enabled and we are not using CRM for Outlook. We are getting errors randomly stating "Could not create the SSL/TLS secure channel."  Below is the full error message. We are getting these errors between 12:30 am - 6:30 am once a morning a couple of times a week for 1 person, not always the same person. We have queried for the ActivityID but it does not exist. The users are not actively working in CRM but may still be logged into CRM & VPN'd while their computers are sleeping. Although, I believe VPN disconnects after sitting idle for a period of time I'm not sure that VPN is an issue due to the time period. We are also on the hunt for a certificate that may have expired but have yet to locate it.  Has anyone experienced this issue? Anyone have any ideas?

    Are you guys using any Exchange load balancer setup with NLB? Have you got more than one Exchange?

    We only have 1 Exchange server and it is load balanced.

    I would investigate the Load balancing side of things as it may be whats causing the intermittent issue you are having

    Thank you for the suggestion. I will ask my team to investigate. I do have another question about the error message. Can you tell me what the ActivityId represents? It does not seem to be an Activity such as Email, Task, Phone Call, as I have searched for the guid and have not been able to locate any of the activity ids  from any of the errors/warnings that we have.

    Thank you,

    Chrys

    ActivityID is part of OrganizationServiceFault, this is not an id for CRM Activities like Email or Task. This activityid in my understanding is generated at the platform level whenever it executes an Organization Request.  If an execution fails (OrganizationServiceFault), it returns this activityid in the error message so that this could be used to investigate further. For example, we can check CRM trace logs with this ID to easily find the logged error.
