I hope this helps

This might be due to a few reasons, try the following steps:

1 Update Service Studio to the latest version.

2 Set NO_PROXY for the domain of your company plus localhost:
   Open cmd and run SETX NO_PROXY "127.0.0.1,localhost,*.domain.com,*outsystems.domain.com", then restart you PC. 
  Obs. replace "domain" by your company domain.
