My PDI dev299704 shows "502 Bad Gateway snow_adc" and won't start

maheshuppara · ‎08-21-2025

Hello,

My personal developer instance (dev299704, release: Yokohama) is stuck showing
"502 Bad Gateway snow_adc" when I try to access it.

The Developer Portal shows the instance as Offline, but the only available
actions are "Refresh" and "Release". I tried Refresh multiple times, but it
remains inaccessible.

Request: Could you please repair/restore this instance without reset, as I have
important data and apps that I cannot lose?

Thanks,
Mahesh

Hi @maheshuppara

It looks like this is a common issue faced by multiple users, including me. I would not suggest releasing the unsynced instance right away. It’s better to wait until today, and if the issue still persists, then you can release the instance and take a new one.

Hi @maheshuppara ,

You have only 2 options - Either Wait or release and get a fresh PDI.

I saw multiple people asking about this error with frequency, so I created this:
