Hi..
Right after installing Confluence, it is connected well except for small issues like messages on the top right side of the screen saying some warning of character-set, inno-db log size related to Mysql DB, but after a few hours, not connected throwing an error like below.
After several attempts of restarting my server the Confluence gets connected well, but after a few hours it doesn't, which means it is unstable unlike Jira, which doesn't have that kind of issues.
