Would you check the attached log?

No i can't see anything major either!
I would either talk to f5 support, or trendmicro support to look at there logs.

I can see connections, and http 200 so connections are happening.  So where the error is and why has to be application side, or at least the information for why may be there!

    Thank you.

    I'm trying to contact F5 support because TrendMicro said it's not their problem.

    Last info: this are logs from F5 console
