Developer instance is offline

[shobhakalya]

Hi, My dev instance dev391594 is offline and giving a 502 error.  Even refreshing it does not help. It was working until this morning. Any help is appreciated. Thank you!

Hi @shobhakalya 

1) Verify instance status
Open:  https://developer.servicenow.com/dev.do#!/instances

Check if your instance dev391594 shows:
Stopped / Hibernating / Error
If yes → click “Start Instance”
2) Wait & Retry (very important)
A 502 error usually means:

Instance node is restarting / overloaded
Backend not responding
Wait ~5–10 minutes, then try again
3) Try direct wake-up URL

JavaScript

https://dev391594.service-now.com/navpage.do

Sometimes homepage fails but backend wakes up from this URL.

4) Clear cache / try incognito
Open in Incognito / Private mode
Or clear browser cache
5) Check if instance expired / reclaimed
If unused for long:

Dev instances get recycled
Data might be lost
Check in developer portal → status will show

 If still 502 after 15–20 mins Raise support request 

If my answer resolves your issue, please accept the solution so it can benefit others.

Hi - Thanks for the response. Actually even this is giving a 404 error.

https://developer.servicenow.com/dev.do#!/instances

And this is still giving the 502error.

https://dev391594.service-now.com/navpage.do

I tried in Incognito mode as well.

Should I just wait for a while?

Thank you!

Hi @shobhakalya ,

• It is backend services issue at your end.  The issue often resolves itself within a few hours or a day once unscheduled maintenance or server updates are completed by ServiceNow
• Open the developer portal in an Incognito/Private window, log in, and launch the PDI.
• Wait for 24 to 48 hours , Hope your issue will be resolved.
• If not,  If the PDI remains offline for multiple days and is critical for your work, release your current instance and request a fresh one from the ServiceNow Developer Dashboard
