Having this error out of sudden, unable to do changes in the access policies and show details (mostly Fabric tab)

How can I solve this?

My friend..

May I ask if you could share more details about this setup? Is this in production ??

The software you are running is more than 10 years old. This was before I even graduated.

In simple words, you need to upgrade ..

Yes, this setup is still in production.

acidiag version
acidiag fnvread
acidiag verifyapic
tail -f /var/log/dme/log/svc_ifc_appliancedirector.bin.log | grep cert
openssl s_client -state -connect 10.0.232.70:12151

Kindly advise.

Thank you.

The oldest ACI software I have ever seen in production was 3.2 ..

I suppose anyone can only advise to upgrade.
Which Hardware are you using? Is it also that old or does the hardware support newer releases?

If the Hardware is also that old.. I would simply build a new fabric next to the existing one and then migrate then endpoints..
