Hi Thijs van Ham!
I have faced the same issue after upgrading iApp from 2.3.0 to 2.4.0. On our StoreFront servers we have the same errors "A request was sent to service '[removed]' that was detected as passing through a gateway. However no gateways are configured for this service." After some research I have found that newer template contains additional HTTP header X-Citrix-Via that BIG-IP was sending to StoreFront servers with each client request with FQDN of the configured Virtual Server.
To my opinion this header must be used for NetScaler and XenApp integration only, not for F5's. Because after you insert this header to StoreFront requests they are trying to find appropriate gateway settings inside XenApp configuration. And of course this configuration could contain Citrix devices only 🙂
Cut from iApp template that need to be commented out:
text`header-insert [expr { $replace_webtop ? "none" : "\"X-Citrix-Via:$::webui_pool__webui_dns_name\"" }] \
PS. Editing template and reapplying it does not resolved my issue. I have to delete and recreate the whole XenApp application on BIG-IP
