Describe the bug
When accessing an outpost after all components were upgraded to 2025.10.0 I get this error (real domain is obfuscated):
{
"Message": "no app for hostname",
"Host": "whoami-xxxx.fqdn",
"Detail": "Check the outpost settings and make sure 'whoami-xxxx.fqdn' is included."
}

To Reproduce
Steps to reproduce the behavior:

Setup an outpost with releases before 2025.10.0 and upgrade it to 2025.10.0. That's all.

Expected behavior
Outpost should behave like with older releasees.
