Hi there,

I have installed FME Flow 2026.1 in AWS has a High Availability WebUI/Core with distributed engines.

The setup uses HTTPS on an internal url (corporate network)

When I try to connect FME Form to Flow, I get the following error message
 

Unable to retrieve public key from Flow
Unable to establish secure communications with Flow
Deployment parameter access failed (Connection Error) - Unable to connect to FME Flow.
 

Has anybody seen this before? Thanks

When I use the url in the browser on the same machine (tested on 2 different machines), i can log in using my admin user account
