IP Load Balancers hijacking letsencrypt/certbot /.well-known/acme-challenge/

hi

anyone know how to get OVH to stop hijacking /.well-known/acme-challenge/ on the load balancers (without changing the loadbalancers from HTTP to TCP mode). This is a result of some new change done by OVH, because my backend servers had no problems before with the renewal of certificates, but now, no /.well-known/acme-challenge/ traffic reaches the backends and some unknown OVH server is responding.

I called support, opened a ticket, but they seem to be unable to solve the problem.

It doesn't happen on all load balancer services, just on some, but it's a weird and recent behavior. A few months ago everything was fine...
