CAS SSO fails for External ticket repository post restart of CAS server

[Casseora]

Currently i am using apereo CAS 5.2.1 . 

I am  using redis as ticket repository . 

SSO works fine if the server instance is not restarted . 

Post restart even providing the same TGC value the server fails to perform SSO and ask for credentials. 

Redis conf :

cas.ticket.registry.redis.host=localhost

cas.ticket.registry.redis.database=0

cas.ticket.registry.redis.port=6379

cas.ticket.registry.redis.password=

# cas.ticket.registry.redis.timeout=2000

# cas.ticket.registry.redis.usePool=true

cas.ticket.registry.redis.pool.max-active=20

cas.ticket.registry.redis.pool.maxIdle=8

cas.ticket.registry.redis.pool.minIdle=0

cas.ticket.registry.redis.pool.maxActive=8

cas.ticket.registry.redis.pool.maxWait=-1

cas.ticket.registry.redis.pool.numTestsPerEvictionRun=0

cas.ticket.registry.redis.pool.softMinEvictableIdleTimeMillis=0

cas.ticket.registry.redis.pool.minEvictableIdleTimeMillis=0

cas.ticket.registry.redis.pool.lifo=true

cas.ticket.registry.redis.pool.fairness=false

cas.ticket.registry.redis.pool.testOnCreate=false

cas.ticket.registry.redis.pool.testOnBorrow=false

cas.ticket.registry.redis.pool.testOnReturn=false

cas.ticket.registry.redis.pool.testWhileIdle=false

cas.ticket.registry.redis.crypto.signing.key=

cas.ticket.registry.redis.crypto.signing.keySize=512

cas.ticket.registry.redis.crypto.encryption.key=

cas.ticket.registry.redis.crypto.encryption.keySize=16

cas.ticket.registry.redis.crypto.alg=AES

 Ticket Conf :

cas.ticket.tgt.hardTimeout.timeToKillInSeconds=28800

cas.ticket.tgt.throttledTimeout.timeToKillInSeconds=28800

cas.ticket.tgt.throttledTimeout.timeInBetweenUsesInSeconds=5

cas.ticket.tgt.maxTimeToLiveInSeconds=28800

cas.ticket.tgt.timeToKillInSeconds=7200

cas.ticket.tgt.onlyTrackMostRecentSession=true

cas.ticket.tgt.maxLength=50

cas.ticket.tgt.rememberMe.enabled=true

cas.ticket.tgt.rememberMe.timeToKillInSeconds=28800

cas.ticket.st.timeToKillInSeconds=7200

cas.ticket.st.numberOfUses=1

Any help is highly appreciated .

Thank you in advance

You can check the contents of redis with the redis command line tool, https://redis.io/documentation.

Do you have the signing and encryption keys for redis and the tickets in the confing file? If not, they will be generated on each start.
