I had a working trust relationship between a WAP and an ADFS farm. Nothing in the environment changed but all of a sudden the trust relationship is broken. Numerous 276 errors on the ADFS server and 422 errors on the WAP.
I attempted to rerun the proxy setup again but it keeps failing:
$cred=Get-Credential
Install-WebApplicationProxy -FederationServiceTrustCredential $cred -CertificateThumbprint 'XXXXXXXXXXXXXXXXXXXX' -FederationServiceName 'fs.xxx.com'
Install-WebApplicationProxy : An error occurred when attempting to save the proxy configuration.
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Install-WebApplicationProxy], ProxyConfigurationException
+ FullyQualifiedErrorId : DeploymentTask,Microsoft.IdentityServer.Management.Proxy.Commands.InstallProxyCommand
Can anyone please provide some insight? Thanks.
Update: It does not seem to work through the F5 load balancer. It just hangs at "Waiting for a proxy trust configuration to be synchronized across farm ........"
