Can anyone please help? Discovery plug-in installation failed 

I got email with this RITM96741601 ticket number as well.

I checked previous post regarding same issue, they asked to wait and check as it might be installed. 

But for me its more than 30 minutes, I logged out and log back in and its still now installed Dev site shows activation failed.

Hi, 

✅ FIRST: Check If Discovery Is Actually Half-Installed

System Definition → Plugins

Search for: com.snc.discovery

If:

• State = Installing

• State = Failed

• Missing entirely

then installation truly failed.

✅ SECOND: Check Plugin Installation Logs

Navigate to : System Diagnostics → Debug → Plugin Installation Log

Filter by: Plugin = com.snc.discovery

You’ll usually see:

• Dependency failure

• Timeout

• Worker aborted

This tells you the REAL cause.

✅ THIRD: Try Manual Reactivation (Works ~70% of time)

If plugin exists but failed:

1. opne: System Definition → Plugins

2. Search: Discover

3. Open Discovery Core

4. Click:

👉 Activate / Repair

✅ FOURTH: Force Re-install via Background Script (Admin)

1. Navigate to : System Definition → Scripts - Background

2. Paste:

        var p = new GlidePluginManager();
        p.activatePlugin('com.snc.discovery');

3. Run

Then refresh Plugins page.

✅ If still fail,

You must: Open Hi(support) ticket with ServiceNow:

You can close this thread i dont see option to close it.  On saturday, I tried again after like 2 hours and i was able to install plug in and it worked well.
I was going to close this thread at that time only but it was pending approval, still not seeing option to close it. 

Thank you for reply.
