Synchrony does not work

[mikegazzaruso]

Hi, I use Confluence Server on a CentOS 7 machine.

Firewall is OK (8090, 8091, 8000 etc.).

I can't modify any page, it says "Editing is not currently available". Synchrony results up and runnings from General Settings, on port 8091, 1GB Heap. 

I must switch to Limited or Off mode in order to edit pages.

I use also Jira Server and Bitbucket Server on the same machines with no problems at all.

DB is PostgreSQL Server 9.2.24.

Dear @mikegazzaruso,

just an idea that popped up above my head: Running Jira + Confluence on the same server; have you modified all the ports in both server.xml files?

So long

Hi @Thomas Deiler

thanks for your reply.

Currently, there are no ports conflicts between the two products, as Jira listens on 8005 and 8080, while Confluence listens on 8090 and 8000 (internal).

I noticed a strange behaviour: If I create a new page, and save it, I am able to edit and save. If I reopen it, the editor opens it. But if make a modify and re-save, I am no longer able to re-edit the page. (This page is running long time etc.etc. warning popup appears and spinner loads forever).

On startup with /etc/init.d/confluence start:

Using Java: /opt/atlassian/confluence/jre/bin/java
2018-10-26 17:55:59,045 INFO [main] [atlassian.confluence.bootstrap.SynchronyProxyWatchdog] A Context element for ${confluence.context.path}/synchrony-proxy is found in /opt/atlassian/confluence/conf/server.xml. No further action is required

is it normal?

Dear @mikegazzaruso,

doesn't look "serious" for me. Do you use apache or nginx in front of Confluence?

Hi @Thomas Deiler, 

I use cPanel on my CentOS machine, but I tried to disable both lfd and csf, with no luck. 

Maybe it's a wrong version of PostgreSQL to cause the issue?

postgresql-9.2.24-1.el7_5.x86_64

Also, I don't use Confluence served by neither Apache nor nginx, it's served by embedded Tomcat/Catalina.

According to the supported plattforms, your DB is not supported. Use 9.4.

I upgraded to 9.6, but no luck.
