Error ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY when using MS Edge

[couqngurt]

Hi,

I have error:

ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY

When using MS Edge to connect to Cognos 11 Analytic Server, which is installed in MS Windows Server 2016. I followed the doc  (https://docs.vmware.com/en/VMware-Horizon-7/7.2/com.vmware.view-agent.directconnectionplugin.doc/GUID-BE0738EC-E35E-4215-8E1E-1F08F911D592.html) to disable HTTP/2 in IIS. There is no such error but my SSO is no longer working. I need to key-in mys user name and password to login Cognos Connection Portal.

Any idea to fix this?

Thx in advance.
