Hadoop web interface is not working even though the nodes are starting

I'm trying to install Hadoop v3.1.3 in pseudo-distributed mode in my Ubuntu 18.04 environment.

After following the documentation word-by-word, my web interface is still not working i.e. localhost:9870 yields no result. Log files are getting created in logs directory but they are empty.

After executing start-all.sh and running jps, it outputs:

14784 DataNode
15689 Jps
14619 NameNode
15228 ResourceManager
15390 NodeManager
15007 SecondaryNameNode

localhost:8088 works fine but no other port for the namenodes, secondary nodes etc.

Following are the config files:

etc/hadoop/core-site.xml:

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

etc/hadoop/hdfs-site.xml:

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>
