Synchrony.port ovverriden, but synchrony do not start


we run Confluence on Port 8091 on a Windows Server.

To use Synchrony on different port i have added 

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\Confluence051118142118\Parameters\Java

  -Dsynchrony.port=8092 to the Options. After reboot i can see in systeminformation, that synchrony.port use 8092, but  synchrony still do not start.

ON Collaborative editing site under configuration is still the old 8091 port. Synchrony do not start.

Is there somebody who could help me?

Best Regards

I found the solution. Just for somebody who has the same problem.

After Change to different port reboot or restart of confluence service did not changed really everything. After change the collaborating Modus off and then again on it works.

please, can you tell what exactly you wrote, what is the line and in which file you wrote?

thank you. 

@Christian Ruf you are a life saver! I was having this same problem and couldn't figure out why Confluence kept showing the old port of 8091. Turning Collaborative mode off and on again fixed the issue--restarting Confluence service alone didn't do it.

Here's the full steps I took:

  1. Turn OFF Collaborative Editing on BOTH instances
  2. Stop both instances of Confluence
  3. Edit one of the instance's Java parameters to use port 8092
  4. Ensure file is deleted for BOTH instances (
  5. Start the instance that you changed in step 3, and turn ON Collaborative Editing
  6. You should see the port update to 8092 now
  7. Start the second instance with the default port of 8091 and turn ON Collaborative Editing

What project did you transition or start on Confluence with the shift to remote work?

It’s been great to hear from fellow users over the last few weeks about the best tips and fun moments you’ve had working on Confluence since the transition to working remote. I’d love to keep the c...
