Confluence problem with Collaborative Editing

[Tomasz Bryla]

Hello,

I have a problem with configuring the proxy in Confluence. I configured by the article available in the knowledge base. However, when I try edit page with collaborative editing I get this error:

Something went wrong after loading the editor. Copy your unsaved changes and refresh the page to keep editing.

 Here my server.xml and proxy configuration. Can anyone tell my where is a problem?

server.xml

<Server port="8000" shutdown="SHUTDOWN" debug="0">
<Service name="Tomcat-Standalone">
<Connector port="8090" connectionTimeout="20000" redirectPort="8443"
maxThreads="48" minSpareThreads="10"
enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
protocol="org.apache.coyote.http11.Http11NioProtocol"
scheme="https" proxyName="confluence.mydomain.com" proxyPort="443"/>

<Engine name="Standalone" defaultHost="localhost" debug="0">
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true" autoDeploy="false" startStopThreads="4">
<Context path="" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true">
<!-- Logging configuration for Confluence is specified in confluence/WEB-INF/classes/log4j.properties -->
<Manager pathname=""/>
<Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
</Context>

<Context path="${confluence.context.path}/synchrony-proxy" docBase="../synchrony-proxy" debug="0"
reloadable="false" useHttpOnly="true">
<Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
</Context>
</Host>
</Engine>
</Service>
</Server>

And my proxy setup

server {
listen confluence.mydomain.com:80;
server_name confluence.mydomain.com;
## redirect http to https ##
rewrite ^ https://$server_name$request_uri? permanent; 
listen 443 default ssl;
ssl_certificate /etc/nginx/ssl/2019.cert.pem;
ssl_certificate_key /etc/nginx/ssl/2019.cert.key;


if ($http_host != "confluence.mydomain.com") {
rewrite ^ confluence.mydomain.com$request_uri permanent;
}

index index.php index.html;

location / {
