Nextcloud Talk Desktop with Load Balancer do not work

[robake1]

First I want to say that when going directly to the Nextcloud server and not using the LB with the same settings and software it works fine, also when turning of sticky sessions in the LB and use source ip Load Balancing instead . Our enviroment has two Nextcloud servers behind the LB and Talk in the WebGUI and other stuff in Nextcloud works fine through the LB with sticky sessions enabled.

Steps to reproduce

1. Put Nextcloud server behind a Load Balancer (LB) with Sticky session algoritm for load balancing.
2. Install Nextcloud Desktop on Windows client (Win 10 or 11) and point to the DNS name of the LB
3. Open a chat in Talk and it will refresh by itself and say "The conversation does not exist"

Expected behaviour

The chat in Talk stays visible.

Actual behaviour

When having a chat in Talk open in Talk Desktop Client (Windows) pointing to the LB DNS it refresh the windows and say "The conversation does not exist"

Were there any other errors? Could you check the Network tab, and what was the error with the conversation request?

What do you use for sticky session?

[robake1]

What do you use for sticky session?

F5 Load balancer , if you mean what product.

[ShGKme]

No, I mean, how the sticky session is configured in your setup.

[ShGKme]

I don't see the F5's default cookie used for sticky session in your response.

[robake1]

I don't see the F5's default cookie used for sticky session in your response.

I will check with my collegue that works with F5 and get back to you with a reply next week.
