Password encryption randomly quit working

Hi all,
I use postman to encrypt passwords in different environments (PRD, ST1, ST2, DEV, CTT).
All of the environments are working but CTT. CTT has always worked correctly and I have not had a problem. For some reason it randomly quit working and is giving me this error Could not get any response. Any ideas?

There was an error connecting to

Why this might have happened:

  • The server couldn’t send a response:

Ensure that the backend is working properly

  • Self-signed SSL certificates are being blocked:

Fix this by turning off ‘SSL certificate verification’ in Settings > General

  • Proxy configured incorrectly

Ensure that proxy is configured correctly in Settings > Proxy

  • Request timeout:

Change request timeout in Settings > General
