Cloudflared tunnel AddressFilter mismatch at the EndpointDispatcher problem

What is the name of the domain?

‘proj.tiaprojserver.online’

What is the error message?

Client call failed with message: The message with To ‘https://proj.tiaprojserver.online/Siemens.Automation.Portal.Server/ProjectRepository/’ cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver’s EndpointAddresses agree.

What is the issue you’re encountering

Third party engineering Project Server app on home Windows 10 server

What steps have you taken to resolve the issue?

Initially I thought that was an authentication problem, but it seems Windows login details get through and server is actually trying to send something over the tunnel although I found this fail massage in Project Sever log file.
I think the server third party application adds /Siemens.Automation.Portal.Server/ProjectRepository/ to the end of the url and tunnel doesn’t like it.

What are the steps to reproduce the issue?

Unfortunately that third part software is needed to reproduce.

Screenshot of the error

At this url when I paste it in browser there is some WCF information screenshot attached.
http://proj.tiaprojserver.online/Siemens.Automation.Portal.Server/ProjectRepository

I tried to create public host name with a additional path, but that doesn’t change anything.
Created another public host, but this time with the path
Siemens.Automation.Portal.Server/ProjectRepository

I think it might by about adding a filter rule to the domain, but I’m not sure what’s the goal here.
