Error when trying to access service manager on new device

[Carol S.]

I was trying to access our company's service manager on a different device than I normally use and received the attached error.  The device is connected to the same network as my regular work computer and should have all the same settings. Would someone know what would cause this error?

HI Carol,

I dont think thats a device related error, I suspect your AD implementation has recently had a new certificate applied, so the Hornbill instance no longer recognizes the signed response from your Idp (most likely Active Directory). Can you talk to whoever looks after your AD/network

Thank you I assumed that it was on my side but wasn't sure what. Thank you I will ask about the AD to our IT team.

Your welcome, I hope you get it sorted out.
