Load Balancer Issues

Hi,

We have a tricky problem that is reaching a dead end.

We use a Moodle LMS and the H5P interactive content activities work as intended if we bypass the Load Balancer.

But when the Load balancer is in use it takes ages to load and is extremely slow.

Has anyone experienced this and can someone direct us on where to check and how to check this, please?

Regards,

PS
