The remote server returned an error: (408) Request Timeout

We are currently having an issue with our Sitecore failover environment, we are getting the message:

The remote server returned an error: (408) Request Timeout

when trying to call Coveo. Our Coveo implementation is on premise and we are using version 8 of the Search API. Our primary and failover Sitecore instances each have their own Coveo services. The failover instance is a mirror of the primary instance. In the Search API log, we have numerous lines with the following message:

00:04:40.115 [AsyncHttpClient-Callback] WARN c.c.search.api.http.IndexHostFactory - Index is still down: https://localhost:52810 (java.net.ConnectException: https://localhost:52810)

Any help in troubleshooting this issue would be greatly appreciate.

Thanks,

Nick

I recommend you open a support ticket with Coveo Support for this issue. This is not the type of issue we can solve without your configuration files and your server topology.

Thanks

Hi @ncipollina,

I can see that the Search API cannot communicate with the mirror index. The first thing to do would be to test the route between the Search API and the mirror. To do that, I suggest you follow this guide and test from the Search API server (replacing CES with your mirror): https://docs.coveo.com/en/637/coveo-for-sitecore-v4/troubleshooting-guide---on-premises-issues#validating-route-4-from-search-api-to-ces

Can you reach the mirror service through the browser remotely when testing from the Search API mirror?

This topology might help give you a better understanding of the infrastructure: https://docs.coveo.com/en/637/coveo-for-sitecore-v4/troubleshooting-guide---on-premises-issues#topology-of-services-and-components

You should also read through the document in it's whole and test relevant routes/components to make sure they are reachable from the required endpoints.

Hi @gbeaudoin

When you say "Can you reach the mirror service through the browser remotely when testing from the Search API mirror?", what exactly do you mean?


Thanks,

Nick
