Agent is unreachable

I'm using EM12cR2 on Solaris SPARC. EM agent became to crash after 2 days network subnet was changed.

How occurs the problem:
1. I started agent
2. After few hours i got a notification
Message=Agent is Unreachable (REASON = unable to connect to http server at https://DSSINVDB01:3872/emd/main/. [peer not authenticated]). Host is unreachable (REASON = Unknown Error pinging the host of URL https://DSSINVDB01:3872/emd/main/.1).
3. After 10..30 mins i got notification that agent became up again.
4. steps 2-3 occured few times per day.
5. After few hours or days agent became unreachable for keeps and didn't restart

./emctl status agent gets the following:
Status agent Failure:unable to connect to http server at https://dssinvdb01:3872/emd/lifecycle/main/. [peer not authenticated]
Agent is Not Running

$ps -ef | grep agent

oracle 21236 1 0 окт. 25 ? 0:53 /u01/app/oracle/agent12c/core/ /u01/app/oracle/agent12c
oracle 24472 21236 0 окт. 28 ? 11:34 /u01/app/oracle/agent12c/core/ -Xmx128M -XX:MaxP

Others agents on other hosts don't have such issue.
I checked logs of EM agent and didn't found any essential errors.
I totally cleared (deinstalled & removed all files) and installed fresh agent binaries on that host. But it also didn't help.

Ntp clients configured...
