I have been working on a CE connector that hosts a small web app and contains internally a http API. For some reason, random files from the Web app and calls to the API get HTTP 503 (Service Unavailable) responses. When I inspect the traffic / URLs used and browse to them independently they respond with expected data and http 200.

Anyone have a similar experience and ideas for debug and fix?

Hi John,

Are you using CE 3.0 ? If not which CE platform version are you using?
If yes , could you try the following steps :

1. Put cluster in denying state
2. Edit cluster
Increase the values of
a) HTTP or HTTPS limit on connections
b) HTTP or HTTPS traffic rate limit in bytes/sec

3. Save the changes and place cluster in accepting mode.

Let me know how that goes..

Thanks

Looks like that was the problem. The cluster was only set to 3 for the http connection limit and the page was trying to load about 10 different CSS/JS files.

Thanks for the help,

John
