Note The full stack trace of the root cause is available in the server logs.

Apache Tomcat/9.0.33

[Nic Brough -Adaptavist- · Accepted solution]

The most common cause of this is that the server Confluence is running on cannot resolve its own name.

See https://confluence.atlassian.com/confkb/confluence-generates-confluence-is-vacant-error-on-install-779164449.html for a full description and fix for that.

[Nouiere Järvinen]

i have two issues why this is not working for me here : this didn't happen during installation we had been using confluence for years and this is a problem that encountred suddenly during night/morning today , second "he hostname does not resolve to an IP address." our hostname DOES resolve to an IP address

[Nic Brough -Adaptavist-]

Is the ip address that the server resolves (not your machine, not a client, the actual Confluence server) the Confluence server?  Just want to check that, I've recently seen this caused by a miskey in a DNS server setting.

The other two things that may cause this error (it's almost always the ip address) are

• an inability for the user running the Confluence service to read and write it's own files - specifically the server.xml and the properties files in the classes directory.  Check the ownership and permissions of the installation and data directores
• The server is unable to reach the database for some reason
