Problem

When uploading a file from the client, the horizontal gauge fills up and after a few seconds, the client displays: Couldn't upload the file.

Diagnosis

• The following lines will be logged in /var/log/hipchat/coral.log:

• The web-app via https://<fqdn>/chat cannot be opened. 

Cause

The network or host information is not properly set in one or many of the following files: 

• /etc/localenv.sh

• /etc/chef/solo.json

• /etc/hosts

• /etc/monit.d/host.monitrc

• /etc/ovfenv.sh

If you're deploying Hipchat Server behind a load balancer then the host information in the files above should point to the DNS name you use to connect to Hipchat Server from your client, also known as your FQDN. 

For example, if you have an AWS ELB (Elastic Load Balancer) with a public DNS <elb_id>.<region_and_az>.elb.amazonaws.com in front of Hipchat Server:

• The files above should not contain this public DNS. Instead, they should point to your actual FQDN: hipchat.<your_domain>.
• The SSL certificate deployed at the ELB has to be the one generated for your FQDN by your CA. 

Resolution

Refer to the resolution steps in Hipchat clients unable to connect to Hipchat Server: Couldn't load Hipchat.
