So, communication from the workflow server(s) to the SharePoint front ends is being blocked? Do you see connection attempts from the workflow servers to the SP VIP? Do you have an APM policy configured on that VIP?
I assume the workflow server is configured using the FQDN of the SP farm and the workflow servers can resolve and route to that virtual server, correct?
When you registered the site with workflow using PowerShell, did you specify the correct protocol (for example, if you are offloading SSL, you'd need to use "https://site.example.com/sitecollection" instead of "http://site.example.com/sitecollection".
Okay, I would first look at the BIG-IP connection statistics for the VIP. Do you see connections to the SP VIP and pool members when workflow attempts to connect?
If you do, you can add an iRule like this one to the SP VIP to log the requests and responses to verify you are seeing requests from the workflow servers:
when HTTP_REQUEST {
log local0. "Request:[HTTP::host][HTTP::uri]:[HTTP::header names]"
foreach cookie [HTTP::cookie names] {
log local0. "Cookie name: $cookie, Cookie value: [HTTP::cookie value $cookie]"
}
foreach aHeader [HTTP::header names] {
log local0. "$aHeader: [HTTP::header value $aHeader]"
}
}
when HTTP_RESPONSE {
log local0. "Response: [HTTP::status]:[HTTP::header names]"
foreach cookie [HTTP::cookie names] {
log local0. "Cookie name: $cookie, Cookie value: [HTTP::cookie value $cookie]"
}
foreach aHeader [HTTP::header names] {
log local0. "$aHeader: [HTTP::header value $aHeader]"
}
}
