For phones to show both tftp address Check the dhcp server option 150. If both act as tftp add both IP as option 150.
Dhcp can be running on your CUCM server or a router or it can be on any windows server inside your network.
check on phone networking settings,it will show the dhcp server details. Check which server is acting as dhcp for phones and check the dhcp configuration.
==============================================================================================
I have my DHCP running on a switch, and below mentioned is the configurations.
ip dhcp pool Voice
network 10.60.51.0 255.255.255.0
default-router 10.60.51.1
option 150 ip 10.60.51.10 10.60.51.11
The below mentioned screenshot is from my phone network webpage. Phone network settings will display the DHCP server IP. You can use this information to identifying the DHCP server if you don't know the server .
If you add both pub and sub on CM group, you gone see both servers on Unified CM information.
==============================================================================================
if DHCP is running on Windows server , option 150 configuration will look like below screenshot.
Go through below link ,how to configure the DHCP on a windows server is well explained on this document.
==============================================================================================
if DHCP is on CUCM, go to DHCP Subnet Configuration page and check if both servers are mentioned on the TFTP.

For second error, are you able to login to publisher ? . What password you reset, application or administrator and on which server you reset ?
Did you check publisher and subscriber Db replication, is it sync ?
Second thing are your trying to login to os admin page or administration page.
There are scenarios where clients keep application password different from administrator password.
You have DB replication issue. that could be the reason you are not able to login from sub. Once you resolve DB check if you are able to login with the old, if not reset the password.
Restart the Cluster and see if Db replications is getting initialized on both servers. can you post utils service list output after cluster restart( issue the command after a delay of lets say 10 min).
One more question, Did you reset the security password ?
There are is two accounts, application and administrator. with application password you can login to CUCM administration , Serviceability page. With administrator credentials you can login to Unified Operating System Administration, DRS, pages and CLI.
i would suggest to involve a partner who is good in voice to avoid major issues.
If not, Don’t change the security password.
Do a cluster restart during non working hours and see if your db gets synced.
If restart doesn’t help resolving the DB, open a TAC case that will be a better option for you.
It’s not totally clear if you have changed the security password on one of your two servers. Have you done this? If so you’ll need to also change it on the other as they need to match.
To have both ip on TFTP , you need to check the Option 150 configured on the DHCP server . CM Group configuration has no role in that.
Your first issue got resolved ?
These are the right commands to reset the username and password for application user.
utils reset_application_ui_administrator_name
utils reset_application_ui_administrator_password
Os admin you can only reset the password, but you cannot reset username. But you can create another users.
I am not sure which password are your trying to reset.
To change the admin PW for the CLI access you would use this command command "set password user admin".
