Why am I getting HTTP Status 404 - Not Found?

Question

I'm very new to Artifactory. I just got Artifactory Tomcat started on my webserver using RHEL 7. When I try to access my page: http://myPage:8081/artifactory/webapp/#/home, I get:

 HTTP Status 404 – Not Found
 Type Status Report
 Message /artifactory/webapp/
 Description The origin server did not find a current representation for 
 the target resource or is not willing to disclose that one exists.
 Apache Tomcat/8.5.32

I've looked around and one solution was to change the http to httpd which I've tried with no luck. Where do I go from here? What logs should I look at? I've looked at catalina.out logs, all I'm seeing are warnings. Thanks in advance for help! Please let me know if their is any other information for me to provide.

EDIT: When I received this warning:

 WARNING: Failed to create work directory 
 [/opt/jfrog/artifactory/tomcat/work/Catalina/localhost/artifactory] for 
 context [/artifactory]. 

I changed my permissions for artifactory.system.properties which is now fine. None of my log files are showing any warning or errors except for catalina.

catalina log:

 web application [artifactory] registered the JDBC driver 
 [org.postgresql.Driver] but failed to unregister it when the web 
 application was stopped. To prevent a memory leak, the JDBC Driver has 
 been forcibly unregistered.

 The web application [artifactory] appears to have started a thread named 
 [Thread-4] but has failed to stop it. This is very likely to create a 
 memory leak.

From what I have seen here: https://stackoverflow.com/questions/36617732/how-to-check-container-log-of-tomcat about "Full details will be found in the appropriate container log." It says to check a localhost.log file. When I check my localhost.log file it show's an error: java.lang.RuntimeException: Properties file artifactory.properties doesn't exist

• jsotola: perhaps you need to read the warning messages
• casper1111: The warning I'm getting is: WARNING: Failed to create work directory [/opt/jfrog/artifactory/tomcat/work/Catalina/localhost/artifactory] for context [/artifactory]. I'm guessing this is a permissions issue?
• casper1111: I changed permissions where the warnings indicated. Still showing HTTP Status 404 - Not Found. Are there any other logs to look at?
• Philippos: Include this information in the question, as it is essential.
• peterh: The warning is a real problem, but probably not this caused the 404.

Answer 1

The warning messages actually have nothing to do with the HTTP Status 404 error.

To resolve this,

1. I restored the access.xml file located here: /var/opt/jfrog/artifactory/tomcat/conf/Catalina/localhost/ by taking the access backup file and copying it as access.xml.
2. It then complained about a missing join.key file. To fix that you need to match the jfrog.join.key.paths variable to $ARTIFACTORY_HOME path variable a the bottom of /var/opt/jfrog/artifactory/etc/default.

After doing these steps, thee artifactory home page now displays.
