Why Does an Exception Occur When I Log In to My Resources Managed in CBH?
Why Does an Exception Occur When I Log In to My Resources Managed in CBH?
Symptoms
- A black screen is displayed when a user attempts to log in to a managed resource.
- The host fails to be connected or is unreachable when a user attempts to log in to the managed resource.
Possible Causes
Cause 1: The managed host responds slowly, and the network connection is abnormal.
Cause 2: The shared bandwidth of CBH does not meet user requirements.
Cause 3: The authorization of the related services on the host expires. For example, the Windows authorization expires, or the 120-day RDP service authorization expires.
Solutions
Solution to cause 1
- Restart the managed host. The network recovers after the managed host is restarted. Log in to the CBH system and check the network connection between CBH and the managed host.
- If the fault persists after the host is restarted, check based on ECS Failures or Slow ECS Responses.
Solution to cause 2
- Reconfigure the bandwidth of the EIP bound to the CBH instance. It is recommended that the bandwidth be greater than 5 Mbit/s. For details about the EIP bandwidth, see How Do I Check Whether the Bandwidth Exceeds the Limit?
- Rectify the configuration and restart the CBH system.
Solution to cause 3
- Renew the expired services on the managed host to obtain required authorization and log in to the managed hosts through CBH again.
