Posted on by JA-27040852-0

In a previous version many moons ago, we had our dual Business Central (On-Premise) Web Servers being load balanced with Microsoft ARR.

For the life of us, we have been unable to do this with BC 22, we are at the point that ARR is forwarding to the Web Servers - but we get error:

If we click Refresh - it just logs the user off.

Thanks, I have seen that and it didn't help with above and auto-logoff.

In my case, it was the missing WebSocket protocol on the ARR Proxy

Hi there

Sounds like you’ve got ARR forwarding requests to your BC 22 web servers, but the session isn’t sticking clicking refresh logs the user off. That usually points to a problem with how ARR is handling session affinity

In older versions, ARR could manage sticky sessions without much fuss, but BC 22 changed how it handles authentication and cookies. If ARR isn’t preserving those properly, the session breaks

Here’s what you can try

Make sure ARR is set to use cookie-based affinity instead of IP-based

Check that it’s not stripping headers like Set-Cookie or Authorization

If you’re doing SSL offloading, confirm that X-Forwarded-Proto and X-Forwarded-For are passed correctly

Enable WebSocket support if it’s not already on BC 22 relies on it more than older versions

Review your rewrite rules and make sure they’re not interfering with session tokens

Let me know what you find. If this helped, feel free to mark it as the suggested or verified answer

Cheers
Jeffrey
