How to Relogon after logout?

Imported from previous forum

Hi,

I receive a Logout message fromAdmin, and sent ResendRequest/TestRequest/Logon messages but no difference. How can I do?

I am afraid you are providing too little information for a too specific problem related to the implementation/counterparty you are working with. I assume you have used FIX 4.4 Volume 2 (FIX Session Layer) or FIXT 1.1 Specification (you do not state a FIX version below) to find out how the session level flows are supposed to work.
A counterparty that logs you out does that for a reason which is normally communicated with the message. That is your starting point to find out what went wrong. Once you are logged out, you have to re-establish the session through a successful logon before you can do anything else.
