ADFS error 102 and 202

Question

Hi, I have been troubleshooting this here for days without any progress,

ADFS running on Windows server 2016, ADFS is using SQL as configuration database, 2 nodes in the farm.

I have enabled adfs trace and nothing suspicous to see there,

I have checked access to private keys, ports are listening, ADFS service is started, but url to adfs metadata is not working, I get connection reset and I can not browse to idpinitatedsignon page ,

ADFS management console is working fine ,

I have checked bindings and all look ok to me. I have run netstat -anon and the only pid listening on port 443 is ADFS

Any help is greatly appreciated.

Kind regards

Gudmundur

but in ADFS admin log I get these errors , its event id 102, followed by event id 202 adn then followed again by event id 102 ,

There was an error in enabling endpoints of Federation Service. Fix configuration errors using PowerShell cmdlets and restart the Federation Service.

Hi. You need to verify the port configuration:-

Get-AdfsProperties | Select httpsPort, TlsClientPort
