GTM Virtual server offline

Hi There,

 

 

Some of the virtual servers (HTTP)at GTM from same LTM are always offline even they are active on the LTM. I have tried different heath monitors like "bigip" "icmp" "http" without success. Not all VMs from that LTM are offline.

 

 

Sometimes ,for the problem VMs, I deleted them and recreated with different IP address, that may fixed the problem

 

 

From GTM, I can ping, http to any of the problem VMs at the LTM. But they are always offline at the GTM Virtual servers.

 

 

Can you please help?

 

 

Thanks you.
