Problems with registering "Service Plugin" from Open Manage Enterprise

Good Morning  , 

I was a little to fast  

When i try to open the Link https://esrs3-core.emc.com/ the the Browser ask me for an Certificate , then i can on my site only choose my own Trusted CA from our CA . 
When i choose this i see this screen : 
The Connection to this Website is not secure . ERR_SSL_PROTOCOL_ERROR

Now i stop on this Point . 

The way you recommend me did not help me. I call technical Support but the Technician on Phone cant help me . 

Good morning, yes that's normal. I also can't reach directly to https://esrs3-core.emc.com/ but as I understand it needs to establish between the appliance and the backend server. I reviewed it again and I would like to share what I found as follows.

• NOTE If SSL decryption is enabled on the proxy servers and other devices, ensure that esrs3-core.emc.com:443 is added to the SSL decryption exclusion list on the proxy servers and devices.
• If HTTPS interception is enabled on the proxy server, the connectivity between Services and Dell EMC backend fails. To avoid connectivity issues due to HTTPS Interception, add esrs3-core.emc.com:443 to the exception list of the proxy server.
• please check that their proxy trusts the following sites:
  • https://esrs3-core.emc.com/
  • https://esrs3-coredr.emc.com/
• To configure the OpenManage Enterprise proxy settings, expand Proxy Configuration.(https://www.dell.com/support/manuals/en-us/dell-openmanage-enterprise/ome_p_3.9_users_guide/configure-openmanage-enterprise-network-settings?guid=guid-95cf0dcc-a2a8-455d-9d5b-3bfe8bf0fd2e&lang=en-us)
  1. Select the Enable HTTP Proxy Settings check box to configure the HTTP proxy, and then enter HTTP proxy address and HTTP port number.
  2. Select the Enable Proxy Authentication check box to enable proxy credentials, and then enter the username and password.
  3. Select the Ignore Certificate Validation check box if the configured proxy intercepts SSL traffic and does not use a trusted third-party certificate. Using this option will ignore the built-in certificate checks used for the warranty and catalog synchronization.
  4. In the Proxy Exclusion List box, you can enter the IPv4 and/or IPv6 addresses or the domain names of the devices that can bypass the proxy server to directly access the appliance.
  5. Click Apply.
  6. To reset the settings to default attributes, click Discard.

I'm not an OME expert but just brainstorming. If the connectivity issues continue it maybe need to uninstall and reinstall the plugin hence the plugin can write fresh security keys.

Ports required to communicate with the Dell EMC backend (reference link https://www.dell.com/support/manuals/en-us/openmanage-enterprise-services/omessupportmatrix2.0.1/network-port-requirements?guid=guid-2f3d0f36-ba26-458e-a1d8-b96d4c85281e&lang=en-us)

Hi , thanks for this Infos . 

With the Link : https://www.dell.com/Identity/global/Login/4882e093-b07c-4465-aa69-2c5c21efdff1?redirectUrl=http%3A%2F%2Flocalhost%2Fsupportassist&instanceId=1837165310%3Fc%3Dus&l=en&feir=1
im now able to Create an OTP . Thats good . 

But under the Link : http://www.dell.com/OpenManageEnterprise/GenerateAccessKey
There is then no Option for me for the PIN registration . 
I was redirected  to Support | Dell Austria . 

Hmm . 

Another Question , is the OpenManage Enterprise Appliance to buy or is it to use without costs ? 
Thanks

I think the software solution team might be helpful about generate access key. Unfortunately, I don't have further information about it. For licenses you can review this pdf it is very detailed. http://dell.to/3BEe8rh

Also, you can try the trial licenses from here http://dell.to/3HE93TG;
