vmware horizon html access edge browser error

We have published RDS apps on Horizon 7.5.1, and any browser except Edge works. Launching an app on side bar just ends up in a grey page. Using UAG in front. First we encountered problem with Edge on logon page, the credentials parts had the spinning circle. Found out that we needed checkOrigin=false on conn servers. After that we succeded in logging on but now we ends up with a grey page, and this is only on Edge. Any ideas?

There are two known issue for HTML Access running on Edge browser through UAG, see VMware Horizon HTML Access 4.9 Release Notes

Copied as below:

If you use a self-signed certificate with Unified Access Gateway, you might not be able to access a Horizon desktop when you use a Microsoft Edge Web browser for your HTML Access session.

Workaround: Use one of the following workarounds to resolve this issue.

  • Use a valid CA-signed certificate.
  • Do not use port 8443 for the Blast External URL property. Use port 443 instead.

or this one:

If you configured Unified Access Gateway with a root certificate that is signed by a Certificate Authority (CA) and the Blast External URL property value is set to blank or to port 8443, you might not be able to connect to  a Horizon desktop if you are using a Microsoft Edge browser. Once the error happens, all new connected sessions are not visible.

Workaround: Use one of the following workarounds to resolve the issue.

  • Set the Blast External URL property to port 443.
  • Close the Micrrosoft Edge browser, then relaunch the HTML Access Web Client and connect to a desktop.
