Load Balancing - 500

Google Cloud Compute Infrastructure
1

Hi,

We are seeing some odd behaviour since approximately, 6.30pm today UK time (5th of July).

We are getting a very specific 500 error message back from our site that appears intermittently

<html><title>Error 500 (Internal Server Error)!</title></html>

The very strange thing is that we can’t find any reference to this particular error, with the ‘!’ anywhere else from a Google search. Which suggests it’s not any open source software generating the error.

From looking at our logs on the backend server we can’t see it generating any 500 errors so we are assuming that it something strange going on with the load balancer.

We have made no code or configuration changes on the site for the last 5 or so days so it is a bit perplexing. It’s been driving us a bit mad as we can’t seem to narrow it down.

We only noticed one other reference to the issue which appeared at a similar time on Twitter which is people mentioning the same error message appearing on https://beta.character.ai/. We also have ‘beta’ in our URL which seems slightly suspicious.

Thanks,
Stephen

Hi @StephenHeron ,

Focusing on the Error 500 showing on your website, indicates an issue with the server-side processing of your website. While it’s not specific to the load balancer itself, it could be related to how the load balancer is configured or how it distributes traffic to your backend servers.

You can check this documentation that explains about Error 500 and troubleshooting steps that you can perform.

Also, if you noticed similar issues encountered on your website, you can check this link . This will show you the possible cause why your website encounters such error message such as the Error 500 which can be related to the load balancer or the backend service, or other Google Cloud related services. If this is the case, you can check it with the support team, let them check your project and determine what causes the error on your website.
