The following kind of message indicates some filesystem issue:

Unable to access /var/log/ambari-server directory. Confirm the directory is created and is writable by Ambari Server user account 'root'

So please check if you have the mentioned directory created and you are able to create some dummy files inside that dir.

# echo "Test" > /var/log/ambari-server/test.log
# mkdir -p /var/log/ambari-server/one

Check if somehow the "/var/log" filesystem has become read-only by any chance? May be rebooting the host will help in such cases.

Also please check if the file "ambari.properties" is showing correct username there:

# grep 'ambari-server.user' /etc/ambari-server/conf/ambari.properties
ambari-server.user=root

Ambari simply makes the following Python call to check if it is able to create directories inside the failing directory with 0755 permission or not?
