Android certificate error

Hi

I have a few honeywell CK65 units and I have loaded the android client to them. When I try and connect i get the following error
Has any one come across this before ?

Thanks

java security certpathvalidatorexception , trust anchor for certification path not found

The certificate that you are using for the flow server URL, is there a way to check if the same certificate exists on the device?

Hi Managed to fix it. There was a certificate missing on the android unit. Adding this and I think it was an older version of the client, so I updated the client and that now seems to work ok.

Thanks
