Certificates implementation in "SSL forward proxy client and server authentication" scenario.

I followed the 11.5.0 procedure but I still have the same error. Here is my current config like posted before:

list ltm virtual VS-TESTVERINT ltm virtual VS-TESTVERINT { destination 172.29.243.27:http ip-protocol tcp mask 255.255.255.255 pool P-TESTVERINT profiles { CSSL-TESTVERINT { context clientside } SSSL-SNVERAPP { context serverside } http { } tcp { } } source 0.0.0.0/0 source-address-translation { pool VIP-TESTVERINT type snat } vlans-disabled }
