PDI 'Wake Instance' action always fails

[keijimiki]

I performed the 'Wake Instance' action because my PDI is in Hibernating state. 
However, no matter how many times I try the action, the PDI does not change from the Hibernating state.

Could you please tell me how to resolve this issue?

Thank you for answering.
I tried the answer, but could not wake up instance.
I release the instance.

This has happened to me before, I reached out to support and they gave me the following steps from KB0011676 (note that these steps are for NowLearning lab instances, but I believe it should work for PDIs as well).

These are the steps from the article (check the article for latest updates/contents):

Sometimes the Instance Hibernation page still appears in your browser even though NowLearning says the instance is 'Running', even after you re-try the URL:

This is likely because the hibernation page is 'cached' in your browser, if this happens, try the following steps:

• Clear your internet cache and close the tab, then try opening the instance again from NowLearning

Mac: 

You will need to be an administrator or elevate your privileges, open a terminal window and paste:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder

PC: 

Clearing DNS Cache on Windows With Command Prompt

Using the command prompt to clear the cache is straightforward:

1. Click on the Start button and type cmd
2. Open the command prompt
3. Enter the following command in the prompt:
   ipconfig/flushdns

PC (IE): Clear Internet Explorer Cache using Rundll32 Command-Line » Winhelponline

• Restart your internet browser
• Try a Private internet browser tab
• Wait a few more minutes for the internet and 'DNS' entries to catchup as the machines get new IP Addresses when they wake up
• Try a different browser if you have that option
• Check to see if a colleague can access the instance OK

---

So try and wake your instances, wait for state to change to it's ready (for me it was providing me with a link to my instance to open it up), flush the dns, then try the instance url.
