Confluence editing/symphony does not work after NIC card change

Lifeng Song

Hi,

I am running confluence server (6.6.1) on virtual machine, recently I have to tear down the NIC card to trouble resolve a network issue, after that I re-installed NIC card with different MAC address, after that I still can log in to confluence, but editing of existing page or creation of new page does not work.
I googled a little bit, and followed instruction to try to disable collaborative editing, the page keeps popping up "Something went wrong, please try again"

A change of MAC should not have affected the setup (IP address maybe). You'll need to read the log files to try to see what has gone wrong.

One quick test though - go to Admin -> Collaborative editing and disable it (temporarily) - can you edit pages ok then?

The have a look at the files in <confluence home>/log - atlassian-confluence.log is probably the first one that I'd expect to see errors in, but there may be others in there. Look for synchrony errors.

Hi I've already tried disabling collaborative editing as I stated in the description:

on the right side keep popping up
"Something went wrong
Please try again."

I went to log folder, there is no log file by name "atlassian-confluence.log"
in file catalina.out , i can see it keeps getting below entries.
Thu Dec 20 08:35:14 EST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification
How can I fix it?

Please look in the application log folder, there is definitely an atlassian-confluence.log file in the <confluence home>/log directory.

Your connection to MySQL is insecure, but not the problem. We need to see the application log errors, not the Tomcat errors.

Hi, I found the confluence log, the failure is caused by unable to retrieve public key for synchrony. the log atlassian-synchrony.log is empty, thanks
