Confluence doesnt start

Question

Hello Community,

i know have essential correct error descriptions are but in this case i have to stay vague, becourse from the logs i cant tell anything which could describe this behaviour.

since friday confluence simply doesnt start up, service and everything is running but all i see is the loading page, not even an error.

i uploaded the logs from service-starting to first access via browser to my dropbox account, maybe you can have a look whats wrong with it.

thank you

Hi Ann, i tried it again today, always the same message:

And than it stays like this. The logfiles dont state anything more than this:

Hi Jens, The logs you posted from /logs show that the Tomcat webserver Confluence uses started up. To find out more about why Confluence is not serving content please check the atlassian-confluence.log in the /logs directory. I look forward to hearing what you find starting from "starting Confluence " onward. Thanks, Ann
