Hi Eric, I have attached a capture of the traffic monitor screen, but caches appear to be ok. I was just wondering if a “null” hashId could be a possible cause, but I don’t know which mandatory data are consumed and tested by the core traffic router, before determining a valid cache server. Thanks Yann

The webpage will show each cache on a separate row with current values for liveness, load avg and bandwidth. You may also want to check the error log on Traffic Monitor to see if its having any issues reaching the edge cache astats endpoint. The current configuration you have below assumes that the edge cache is listening on the eth0 interface.

I am wondering if the CR config below is ok ?
