confluence not allowing page edits
Asked by Reg Hawkins:

I have confluence running in a docker container and have only a few ports open.

I can see the page (i'm logged in as admin) but then when I edit the page do I need to open up more ports in my firewall? if which ones.![confluence not editing.PNG](/t5/image/serverpage/image-id/12892i06528BEDD019809A/image-size/large?v=v2&px=999 "confluence not editing.PNG")

Confluence 6.5.0 - Standalone  

<br />

After some digging I found old file synchrony.pid was never refresh on restart  

Stopping confluence service and deleting old confluence/temp/synchrony.pid did the trick  

Then I started service again, file synchrony.pid was newly generated and Collaborative Editing works

body: i have the same problems. Only cancelling the Synchrony funftion, makes it possible to edit a page. In the same constellatoin it works for about 6 weeks. but from one day to another it wont works any longer.  
Windows updates responsible? Port and everathing else hadn?t been changed.

The error you saw can be caused by a lot of things, and looking in the logs should ultimately help you narrow down the issue.

If that article above doesn't fix your issue, you can have a look here:

* [Collaborative Editing and Synchrony Troubleshooting](https://confluence.atlassian.com/confkb/collaborative-editing-and-synchrony-troubleshooting-858584399.html)
* [Troubleshooting Collaborative Editing](https://confluence.atlassian.com/doc/troubleshooting-collaborative-editing-858772087.html)

Be advised that Synchrony runs on port 8091 by default.

Once you solve your issue you can let me know and I'll accept your answer as resolved. :)

Regards,

Shannon

body: currently I have confluence running in a docker container and it is using a local host but I have confluence running on 172.28.1.4 is there a way to change the ip address synchrony works on


author: Shannon S
body: Hi Reg,

It appears you may be able to modify it using a System Property:

* [Recognized System Properties](https://confluence.atlassian.com/confeap/recognized-system-properties-480347012.html)

Perhaps this one:

|-------|-----------|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| ##### synchrony.host {#toc-hId-1199118778}                                                                                                                                                                        ||||
| 6.0.4 | 127.0.0.1 |   | This is the IP that Confluence uses to connect to Synchrony. It defaults to localhost. Change this if you need to allow Confluence to contact Synchrony via a custom hostname or IP address. |

See [Change your Synchrony Configuration](https://confluence.atlassian.com/confeap/administering-collaborative-editing-847355676.html#AdministeringCollaborativeEditing-ChangeyourSynchronyconfiguration) for further details.

I haven't personally experienced changing this myself but it should help you to get started there.

Shannon
