I am getting this error unexpected JWT alg received, expected RS256, got: RS512 when using the openid connection. After entering my credentials on ping federate I am getting the said error. Do I need to change any of my configuration on my application? Thanks.

Hello @dan.woda . For now we had changed the Ping Federate configuration to RS256 and this solved now the issue. Thank you.

Hi @jearson , Yes, it sounds like your token is being signed with RS512, and the application verifying the signature is expecting RS256.

Thanks for the update, I am going to mark this resolved.
