Resource Error: Network request failed / 503 HTTP code on api/ws

[morodest]

Hello!
Sometimes I get 503 errors in cloudbeaver logs. Log file in the attache:
cb_error_session.log

It looks like the client is connecting to the server from an old session, but it has already been deleted. How can I increase the session lifetime or otherwise fix this error?

To Reproduce
Steps to reproduce the behavior:

1. Open cloudbeaver in browser
2. Do nothing
3. Sometime you will get this error

Screenshots

Additional context
Our Cloudbeaver CE hosted on the kubernetes cluster with Istio service mesh
Backend version: 24.1.3.202407220833
Frontend version: 24.1.3.202407220836

Hi @morodest
We can't reproduce that on our side. The problem seems to be with websockets. It would be very helpful if you provide us with any extra information.
What server setting do you have?
Have you changed the default CB configs?
When exactly the error appears? If you open CB and do absolultely nothing, don't even authenticate?
How do you authenticate? (auth log will also be useful)
What helps you after the error? Page refresh or server restart?

Hi, @EvgeniaBzzz
The problem is more often reproduced in Safari when we work via VPN. If you leave the screen open for some time, you can get a 503 error.

When exactly the error appears? If you open CB and do absolultely nothing, don't even authenticate?

Just after authentication. I opened CB in Safari, logged in and didn’t touch it for the next hour.

How do you authenticate? (auth log will also be useful)

with local AuthProviders. Where I can find auth log?

What helps you after the error? Page refresh or server restart?

Refreshing the page is enough

We get errors quite often.

Thank you!

Hello @morodest

Please update your CloudBeaver version and check if your issue still exists.
