Appear to have just encountered this in X12.6. Anyone else had this issue in that release?

Had what appeared to be this issue after upgrading from CUCM 11.5.1 SU4 to SU8. Post upgrade, cert validation was failing for UDS, so MRA phones could not authenticate:

We rebooted EXP-C and that cleared the issue. We did not have to do the workaround listed in the bug report.

Good to know. We just encountered it again in X12.6.4. Frustrated by all the "workarounds" in this platform versus bugs being fixed by the BU.

X12.6.2 with CUCM upgrade from 11.5 to 12.5 - same issue. Cluster restart proposed by TAC "resolved" it.
