Sensuctl configure needs to be reconfigure each time (sensu-go-backend and sensuctl version 6.10 )

Hi ,
After I configure sensuctl for sensu-backend cluster , it works fine for one day. Next day when I try to access webUI or events,checks with sensuctl, I need to again reconfigure it. I configure it using below command

sensuctl configure -n --url http://127.0.0.1:8080 --format tabular --username <YOUR_USERNAME> --password ‘<YOUR_PASSWORD>’
What is the reason behind this reconfigure, I couldnot figure it out. Sensu-go-backend and sensuctl cli are of version 6.10. To my understanding, sensuctl once reconfigure, remains for longer.
