Found a trick that does work. You can only do this if you are on site. The embedded file management won't load the certificate. Gives a 403 error. Forbidden.
Download the certificate with web manager.
Pull the SD card out of the IPO and put it in your PC.
Copy the certificate to the system/primary/certificates/tcs/delete
Reboot
From the readme.txt in that folder.
This folder contains certificates that should be automatically deleted from the IPOFFICE
Trusted Certificate Store. The system can interpret both PEM and DER encodings. The
certificate file name extension must indicate the type of encoding. PEM encoded files
should end with .pem and DER encoded files should end with .der.
When the IPOFFICE boots, the system will check if there are any certificates that exactly match
a certificate in the TCS (byte for byte). If a matching certificate is found in the TCS,
it will then be removed.
Or you can ignore the SSA error.
