  • A service tries to bind to a address/port combination that is already in use by another service (or an other instance of the service). – Klaus D. Apr 22 '21 at 06:37
  • @KlausD. when i typed ps, there's only 1 process is running under that pid. I killed it and tried it again and still the same error comes. – Vishwajith Fernando Apr 24 '21 at 03:01
