Error since 1.19.50 update

I cannot connect to a server in azure container instances since the 1.19.50 upgrade. Creating a container using the example
`az container create --resource-group rg-mine --name minecotainer --image itzg/minecraft-bedrock-server --dns-name-label minesvrbedrock --ports 19132 19133 --protocol udp --restart-policy OnFailure --environment-variables EULA=TRUE `

And the container responds to pings but is not connectable. Rolling back to previous 1.18 version and world is connectable

Reproduce the issue with the shown `az container create` command in Azure Container Instances using the 1.19.50 image, then compare it with the previous 1.18 version. Check whether UDP ports 19132 and 19133 remain reachable; done means the container is connectable without reverting versions.
