@vaibhavm You need two steps process.
1. Disable TLS for CM so that you can access Web UI, for this follow below instruction.
Disable TLS for the CM:
1. Determine Cloudera Manager Database
cat /etc/cloudera-scm-server/db.properties
2. Make database backup
3. get inside the DB.
#mysql --user=cm --password=cm
#mysql> show databases;
#mysql> use cm;
4. Show TLS related rows
select * from CONFIGS where attr like '%tls%';
5. Update TLS for web_tls
update CONFIGS set value = 'false' where attr = 'web_tls';
6. Update TLS for agent_tls
update CONFIGS set value = 'false' where attr = 'agent_tls';
7. Show TLS related rows
select * from CONFIGS where attr like '%tls%';
8. Restart Cloudera Manager server process
service cloudera-scm-server restart
2. At this stage you will be able to successfully login into CM Web UI. Now you can disable Auto-TLS (If already enabled) using below method.
--remove the line in /etc/default/cloudera-scm-server that loads cm_init.txt on startup
--then you can turn off TLS in the web UI and remove the TLS configs from the agent config.ini
3. Then you can follow the doc which @Mike in Austin refereed in his comment to enable TLS again from fresh.
Cheers!
