My application has 57 microservices.we are reducing it to 7 jars.I created new microservice and consolidated everything which is working fine when I make an api call from Frontend to backend.but after keeping this microservices in QA server if make an api request from frontend to backend it shows 401 unauthorised error .if it works in my local then why not in QA?

I checked the application .yml file,configuration files and Api request filter and CORS filter (allowed *) I tried but still same error
