Trouble accessing CHRTAS?

We are aware of an issue affecting some users when they attempt to access CHRTAS. Specifically, users are seeing an error message stating "Can't connect securely to this page. This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website's owner."

We have been in contact with the engineers at ATRRS/CHRTAS, and they have provided the below information and resolution instructions. If you are experiencing this issue, please provide this information to your local IT support desk. It is our understanding that a certificate issue will need to be addressed at the user-level.

"The connectivity issue is not specific to the ATRRS system. The operations team has confirmed this issue is widespread affecting many DoD systems. The trigger is unknown but appears to be related to workstation configurations that allow cross-chaining of certificates.

To resolve this issue, a user's workstation certificates must be re-configured. The ATRRS helpdesk has re-configuration instructions that have worked for some users. The solution has not worked for all users and in some cases has not permanently resolved the issue. The reference information below also has a solution for re-configuring certificates.

We recommend users contact their local IT support team in order to ensure a permanent solution is put in place in compliance with local configuration and security policies.

Reference: and scroll down to the Certificate Validation section. Download and run the FBCA Cross-Certificate Remover Tool 1.17."
