Confluence behind Sophos UTM with WAF (reverse proxy)

[Vijay Atturu]

Hi all,

when we use our single Confluence installation in the internal network everything works fine. Now we have to share it with external partners and I setup  our Sophos UTM to reach the Confluence website via https://sub.myDomain.com:8443 (forwarded to http://localIPaddress:8090)

I am able to login, read contents, create spaces and setup parameters as Admin. But I can't create content.

After awhile I get the hint Tomcat config is incorrect:

But in the server.xml the parameter are correct.

I tried another port, I also tried it with a context path like https://sub.myDomain.com:8443/confluence

Anyone else have any ideas?
Any help is appreciated.

Thanks

best regards
