Problem:

VMware Applvolume giving error "Error From Manager (Error Code 401) Invalid Session Cookie: Session Key Does Not Match Any Active Sessions". Users are failed to connect the AppStack.

Reason and Solution

Reason 1:

As per VMware knowledge base, the issue is happening because of additional authentication calls for Agent-Manager communications and solution is to disable "Agent Session Cookie feature"

Refer KBASE for more details.

Reason 2:

I faced this issue recently, after long troubleshooting I identified issue was with vCenter. vCenter was not accepting any users to login, Then I identified VCSA appliance was out of disk space and I fixed issue by clearing the audit.log.
