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 https://springconfigctt.pearsonvue.com/ConfigServer/encrypt.

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
