502 proxy error trying to login to jira

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,

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 ?

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