Hi @rubysarda,
I don't see any error related to phpMyAdmin in your logs, but I see one about not enough disk space.

I see you fixed that issue, but I don't know if it has any relationship with the phpMyAdmin issue.

Can you SSH connect to your server and run the next command?
curl -LI "http://127.0.0.1/phpmyadmin"
After that, can you start the SSH tunnel again and run the next command from your computer?
curl -LI "http://127.0.0.1:8888/phpmyadmin"
I also see a lot of PageSpeed errors in the Apache logs. Can you try to disable it?
