can't access to my virtual server

I think you're vip is on 443, but your not offloading anything on the LTM but have applied http profile. You can try out the below options.

• Add the default client ssl profile.
• Try removing your http profile and see the behavior.

To help this understand, when you send the traffic over secure (https - your vip is on port 443), the ltm needs to know what traffic its receiving and process it accordingly. When you apply http profile, it is expecting a http traffic and can process only http functionalities. But without offloading it on the ltm, its still a https traffic. So flow breaks, to avoid this, you can offload it first using a clientssl profile and then inspect the layer 7 attributes.
