The error is somewhat generic so it requires analysis on the debug log and hence TAC cases. One known issue is CSCvc28209.

Thanks

I don't understand the workaround mentioned in CSCvc28209:
Workaround:
identity overrun property field and set back to default

One case is due to English.properties file field “ui_client_provision_posture_check_non_compliant_message” is extremely large. There might be other situations running into this error so best to have TAC to help debugging.

Thanks.

That hint solved my problem.
The field "key.guest.ui_client_provision_posture_check_non_compliant_message" in the english.properties file was very long, and with crypto-like text.
