Hi @RAJENDRANR
This has been a known issue since yesterday.
It may be due to planned or unplanned maintenance on ServiceNow's end, which typically isn’t communicated to PDI users.
You have a few options:
-
Wait it out – often, the issue resolves itself after a few hours.
-
Release and request a new PDI – if urgent.
-
Try accessing through alternate methods:
-
Log in to developer.servicenow.com and launch the PDI from there. Some users have reported success using this approach.
-
A workaround suggested by my friend @Nikhil Bajaj9
Open developer.servicenow.com in incognito mode, sign in, and launch the PDI. While it may show a security error, scroll down and click the ‘Advanced’ option in the footer. Then, click on the ‘Proceed to <PDI URL> (unsafe)’ link to bypass the warning and access your PDI.
-
Unless it's urgent, it’s recommended to wait a bit before deciding to release the instance.
If my response proves useful, please indicate its helpfulness by selecting " Accept as Solution" and " Helpful." This action benefits both the community and me.

Hi @RAJENDRANR .
It is happening as ServiceNow SSL certificate is expired so it is navigating you to http:// rather than https://. Many other people are affected by this and hope it will be fixed soon by ServiceNow.
Work Around: - Open developer.servicenow.com in incognito mode and sign in and launch PDI. It will display error, but it will also display Advanced option towards footer. Click on it and on next screen click on "Procced <PDI URL> unsafe" link and you will be able to access your PDI.
