This issue can be observed while updating a change from the console and saving and activating the changes or in this case from Enterprise manager console trying to edit a configuration and got the below error in the process and the same was seen in AdminServer logs too.
<Apr 4, 2017 9:19:34 AM PDT> <Warning> <DeploymentService> <BEA-290015> <Domain wide secret mismatch>
<Apr 4, 2017 9:20:34 AM PDT> <Warning> <DeploymentService> <BEA-290015> <Domain wide secret mismatch>
Failed-server: server2, Reason: java.rmi.RemoteException: [Deployer:149150]An IOException occurred while reading the input. : with response code ‘401’ : with response message ‘Unauthorized’
Edit-owner: principals=[weblogic, Administrators], Exclusive: false, Acquired: 1491322469714, Expire: 0
Possible Reason
1) Significant time delay between Admin and Managed Servers
Validation
1) Check the time on both admin servers, if there time difference is more then 2 mins / 120 sec then please proceed further.
# date —–→ Command Can be used to validate time on unix/linux systems
2) Check NTP configruations
# ntpq -pn —→ will list out the ntp servers if configured.
Sample
———
[root@host01 ~]# ntpq -pn

3) Run a time check on ntp server to see if it is working, using ntpdate -dv command
# ntpdate -dv <ntp server ip>
Sample

[root@host01 ~]# ntpdate -dv 10.232.144.1

4 Apr 15:12:23 ntpdate[1014]: no server suitable for synchronization found
[root@host01 ~]#
In this case NTPServer isn’t responding so that’s the reason there was time delay between WLS servers
4) Use ntpdate -uv command to manually sync the server with active working ntp server.
# ntpdate -uv <ntpserver ip>
[root@host01 ~]# ntpdate -uv 192.0.2.1

4 Apr 09:42:34 ntpdate[31627]: step time server 192.0.2.1 offset 116.684819 sec
run the above command on all wls server to make sure time is sync, then run date command to verify.
5) Now try to update wls settings changes from admin console, it should work.
