Posting this here to add to the traffic. I know my options but if ServiceNow could fix our cluster

Sometimes the instance's backend is running but the SSL handshake fails in standard browser tabs.

Open the ServiceNow Developer Portal in an Incognito / Private window.
Sign in and attempt to launch your PDI.
If a security warning appears, look for and click Advanced, then select Proceed to [Your PDI URL] (unsafe)

Alternative: If waiting does not work and you urgently need a working environment, you will need to wipe or release the PDI:

Log into the ServiceNow Developer Site.
Go to your My Instance panel, click Actions, and select Reset and Wipe Instance or Release Instance to start fresh.
Warning: Doing this will erase all configurations, custom apps, and data on your old instance

Thanks I gave it a shot but still says Bad Request: This combination of host and port requires TLS.

Wait for some time.
