I have tried to setup IFS 10 TAS server in web farm and followed the installation quide firmly. But it always ends up with an exception on the second node where the authentication proccess endsd with this fault

ExecuteAuthentication.CryptographicException: Error occurred while decoding OAEP padding..

The touch app server certificate has been exported and imported on the second node. and alll documented access is granted. Still same issue. 

I have tried to switch places on the node but it’s always the node the sertificate is imported to that failes with ExecuteAuthentication.CryptographicException: Error occurred while decoding OAEP padding..

Running on windows 2022 server. Anyone seen this behavior ?
