Troubleshooting
Problem
Cognos Analytics website is not responding and eventually returns with "HTTP Error 502"
No access to the site is possible.
Symptom
The application URL is working and access is fine. (http:server:9300/bi)
Cause
The IIS rewrite rules are not routing requests appropriately.
The Reverse Proxy rule is using the incorrect protocol. Https vs http
Environment
Windows install that uses IIS
Resolving The Problem
To resolve the matter, ensure that the protocol used by the application (HTTP or HTTPS) is used in the Reverse Proxy rule.
e.g. application URL: http:server:9300/bi -- Rewrite url should be : http://<server>:9300/bi/{R:0} or http://ca_server/bi/ (if using server farm)
https:server:9300/bi -- Rewrite url should be: https://<server>:9300/bi/{R:0} or https://ca_server/bi/ (if using server farm)
Once the change is made, apply the change and recycle the IIS application pool.
