Troubleshooting Question
I’m encountering an issue with the Exchange Control Panel (ECP) when trying to access it through an SSL domain. The problem is that ECP displays the error message: “Sorry, your request couldn’t be completed. Try deleting the cookies from your browser, and then sign in again. If the problem continues, contact your email admin.”
However, here’s the interesting part: when I access ECP using the IP addresses of the servers, it works perfectly fine. It’s worth mentioning that the servers are operating under a LoadBalancer.
I’m seeking guidance on how to resolve this issue and understand why there’s a discrepancy between accessing ECP via the SSL domain and the IP addresses. Any insights or solutions would be greatly appreciated.
Solution: Addressing Load Balancer Configuration Issue
The problem you’re encountering with the Exchange Control Panel (ECP) likely stems from a configuration issue with the load balancer. It appears that the Load Balancer isn’t set up to maintain session persistence.
To address this issue, consider the following steps based on your specific use case:
- Internal Connections: If the load balancer primarily serves internal connections, you can implement session persistence based on IP addresses. This means that requests from the same IP address will consistently be directed to the same server, ensuring a smoother ECP experience.
- External Connections: If your load balancer handles a significant number of external connections, it’s advisable to opt for persistence based on cookie sessions. This method utilizes cookies to track and maintain user sessions, even when requests are distributed across multiple servers. It’s a more robust solution for external users who may have varying IP addresses.
By configuring the load balancer to maintain session persistence through one of these methods, you should be able to resolve the ECP error and ensure a more reliable and consistent experience for your users.
