Connection error after memsql to singlestore migration

We have migrated the memSQL database from memSQL to singleStore. End-user permissions are entact but application can not connect. I have very limited knowladge of memSQL, any thoughts or trouble shooting will would help. These are the erros we recived in the application log.

Failed to establish MemSql connection { Error: ER_ACCESS_DENIED_ERROR: Access denied for user ‘web_session_api’@‘10.10.128.54’ (using password: YES)
