This article contains debugging tips and checks to perform when you get errors trying to install Apps from the App Catalog.
The App Catalog supports the following versions of K2:
Using a web browser, try to browse to https://appcatalog.onk2.com.
You should see one of the following two outcomes. If either of these outcomes are true, you are able to reach the K2 App Catalog service and a firewall is not blocking communication. If you do not see any of the outcomes listed below, it is likely that a firewall is blocking access to the K2 App Catalog service, and you will need to address the firewall restriction before trying to access the App Catalog service again.
If you are on K2 version 5.x, please review your K2 host server's log output for any additional details or errors. Location of the log files depend on your logging configuration, but you may typically find this information in the Event Log of the server hosting the K2 Service, or in the following directory: "[Program Files]\K2\Host Server\Bin".
If you are on K2 Five, and are able to reach the K2 App Catalog service as described above, but still cannot see a list of Apps from the Catalog, please contact K2 Product support and request the ‘App Catalog Communication Check Utility’.
This utility needs to be run on the K2 Five application server, and needs to run in the context of the K2 Server service's service account. Once the utility has completed, an expected success outcome should look like the image below.
If you do not see successful output, please log a support ticket with K2 Product Support, and include the log file generated by the utility (Click the Download Log File button in the utility to download the log file), as well as the K2 server logs as described in ‘Check Host Server Log output’ section above.
