502 proxy error trying to login to jira

[Navadeep M]

Hi All,

Need quick help please.

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.

Reason: DNS lookup failure for: jira.dev.<company.edu>

Apache/2.2.15 (Red Hat) Server at jira.dev.<company.edu> Port 443

Thanks,

Navadeep

If the DNS lookup error is to be believed, you could try putting the hostname of your server as a loopback in the hosts file:

/etc/hosts - append to bottom:

127.0.0.1 jira.dev.<company.edu>

If it's not actually a DNS error, you probably have a typo or other error in your proxy configuration in apache.

Thanks for quick response Josh.

Checked the /etc/hosts file

It looks fine. 

The error also shows below

Apache/2.2.15 (Red Hat) Server at jira.dev.<company.edu> Port 443

What exactly do I need to check in the proxy configuration file in apache 

Thanks,

[josh]

I assume it's /etc/httpd/conf.d/ssl.conf

If you followed the documentation, there should be some parts you added to handle the proxy, such as ProxyPass and ProxyPassReverse directives. Also you should have modified the standard /jirainstalldir/conf/server.xml

Did you use this documentation page? https://confluence.atlassian.com/adminjiraserver073/integrating-jira-with-apache-using-ssl-861253896.html

I checked the ssl.conf.

SSLProxyEngine                On
ProxyRequests                  Off
ProxyPreserveHost           On
ProxyPass                         /      http://jira.dev.<company.edu>8080/
ProxyPassReverse            /      http://jira.dev.company.edu:8080/

It is showing as above.

in Server.xml what things I need to check clearly.. 

Thanks,

You'll need to have a connector object in server.xml like this:

        <Connector port="8080"

                maxThreads="150"
                minSpareThreads="25"
                connectionTimeout="20000"

                enableLookups="false"
                maxHttpHeaderSize="8192"
                protocol="HTTP/1.1"
                useBodyEncodingForURI="true"
                redirectPort="8443"
                acceptCount="100"
                disableUploadTimeout="true"

                scheme="https"
                proxyName="jira.dev.company.edu"
                proxyPort="443"
                secure="true"/>

<Connector port="8080"

maxThreads="150"
minSpareThreads="25"
connectionTimeout="20000"

enableLookups="false"
maxHttpHeaderSize="8192"
protocol="HTTP/1.1"
useBodyEncodingForURI="true"
redirectPort="8443"
acceptCount="100"
disableUploadTimeout="true"

proxyName="jira.dev.company.edu"

scheme="https"

proxyPort="443"
secure="true"/>

Above is the content how it is defined in the file.. It also looks fine I guess.. 

Any other reasons why I am not able to access still ? Or restart JIRA will help out anyway ?

[josh]

If you haven't restarted JIRA since modifying the server.xml, you need to do that.
