Hey @bukky-oe 
Welcome to the Postman Community! 
What do you mean by “I’m stuck in Scratchpad”? Which version of Postman are you using?
@danny-dainton The issue seems to be that the “Switch to Workspace” screen doesn’t use any custom certificates loaded via Certificates > CA Settings. That JavaScript error that @navigation-meteoro16 posted is exactly the issue I’m experiencing (I’m on Version 11.1.14, Postman for Linux, Architecture x64).
This is specifically an issue for companies using MITM style proxy systems.
I just had the same error and resolved it by logging in here (postman community) via browser.
After that when I started Postman I got the Windows firewall alert, allowed it and it started working again.
Probably it had some issues to refresh the authentication tokens with postman.com.
disclaimer: an image here is for the information purposes. I had the same alert but for Postman.
