Logs isn't showing in kibana

Dear Team,

Due to certain server dependency problems, my Elk server recently crashed. To recover Elk, I used an old Elk snapshot of the server and updated all configuration settings for the new IP.

unable to access the server log in the Kibana console. Could you please assist with debugging the problem.

When attempting to retrieve the latest version of Kibana from the server, the following error was received.

root@elk:/var/log/filebeat# /usr/share/kibana/bin/kibana --version
fs.js:114
    throw err;
    ^

What does /var/log/kibana/kibana.log show?

@warkolm Thanks for your reply.
logs not processing in kibana.log file but kibana service running fine.

Please suggest me to debug the areas to fix this.
