sharing between instances not possible

trying to share an eCMR between to instances ran into an error and the eCMR was not able to take over. As the frontend and backend is available on the same server and has nearly the same address, it is not possible to share the eCMR. The address in the backend needs to be shared in order to be able to share the eCMR. If the address would be changed in the backend, this will lead to problems with the frontend as the frontend uses the same address as hard coded in the backend.

Further details:

backend address: ecmr.app.rhenus.com/api this address is the address that is shared to access the eCMR. The application itself adds to any address "/api" which means the address gets wrong and the eCMR cannot be accessed (address would be then: ecmr.app.rhenus.com/api/api)

in order to prevent this, the "/api" needs to be removed in the code, but as the frontend is using the same address, frontend won't get the connection to the backend anymore.

During testing it was possible to access the eCMR by manually removing the "/api" from the address.
