Stuck in stopping state

Hello there, I have launched EC2 instance with hibernate mode enabled from custom Ubuntu-20 based AMI. When I choose hibernate option for this EC2 instance, its taking more than 20 minutes to change from stopping to stopped state. I don't know why its taking this much time to take stopped state. I tried with multiple EC2 instances from this custom AMI. All launched instances from this AMI, taking more than 20 minutes to stopped state. I increased my root volume size too, now this root volume has more than 15 GB free space. However, its still taking more time to stopped state when I choose hibernate option from console. I can see the hibernate related logs from /var/log/syslog. Can any one please help me to outdo from this issues? > Sep 27 12:17:41 SparxEA systemd[1]: Starting EC2 instance hibernation setup agent...

What to look at for resolving Nice DCV 404 errors

I've got an EC2 instance setup with Nice DCV. I have setup port access in my security rules and created a session in nice dcv. However, whenever I try to connect to the session via the browsed, I get an HTTP ERROR 404. I can't seem to find any information in the Nice DCV docs about causes of 404 except for the session resolver which I'm not using. How can I go about resolving this issue? Below is the output from dcv list-sessions -j ``` [ { "id" : "cloud9-session", "owner" : "ubuntu", "num-of-connections" : 0, "creation-time" : "2022-09-23T12:58:40.919860Z", "last-disconnection-time" : "", "licenses" : [ { "product" : "dcv", "status" : "licensed", "check-timestamp" : "2022-09-23T12:58:42.540422Z", "expiration-date" : "" }, { "product" : "dcv-gl", "status" : "licensed", "check-timestamp" : "2022-09-23T12:58:42.540422Z", "expiration-date" : "" } ], "licensing-mode" : "EC2", "storage-root" : "", "type" : "virtual", "status" : "running", "x11-display" : ":0", "x11-authority" : "/run/user/1000/dcv/cloud9-session.xauth", "display-layout" : [ { "width" : 800, "height" : 600, "x" : 0, "y" : 0 } ] } ] ``` This is the output from dcv get-config ``` [connectivity] web-use-https = false web-port = 8080 web-extra-http-headers = [('test-header', 'test-value')] [security] authentication = 'none' ``` This is the output from systemctl status dcvserver ``` ● dcvserver.service - NICE DCV server daemon Loaded: loaded (/lib/systemd/system/dcvserver.service; enabled; vendor preset: enable> Active: active (running) since Fri 2022-09-23 12:58:40 UTC; 18min ago Main PID: 715 (dcvserver) Tasks: 6 (limit: 76196) Memory: 39.9M CGroup: /system.slice/dcvserver.service ├─715 /bin/bash /usr/bin/dcvserver -d --service └─724 /usr/lib/x86_64-linux-gnu/dcv/dcvserver --service Sep 23 12:58:40 ip-10-0-0-115 systemd[1]: Starting NICE DCV server daemon... Sep 23 12:58:40 ip-10-0-0-115 systemd[1]: Started NICE DCV server daemon. ``` I'm trying to access the page with http://<public ip>:8080 I've also tried including the #session_id part in the url and using the windows client with no luck. My operating system is Ubuntu 20.04 with a custom AMI running in a g4dn.4xlarge machine.
