I don't know how MARS will react on TLS-certificate regeneration but I know that you'll not add sensor to IPS without certificate renew.

It will be very difficult procedure so I say "no, it is impossible to revert to old certificate". But it is interesting that MARS doesn't say you any warning about certificate expired in Jul, 22.

Your TLS certificate on the sensor is expired.
Login to sensor CLI and regenerate it by command:
tls generate-key

do that have any relation if i have cs-mars in place that is collecting logs?
in other words, can ips report logs Simultaneously to cs-mars and ime right? and my problem is not related to this issue?
if so then tls generate key will not affect the IPS config on CS-mars right?

Your problem is only in certificate expiration as I can see it.
What protocol do you use in MARS<->IPS relationship?

Access type is SSL!
