If you created your brand new docker container with the help of BCHelperConatiner, tried logging in to Business Central Web Client, and received the below error?
You cannot sign in due to a technical issue. Contact your system administrator.
Don’t worry. You are not alone. If you google the error, you will notice that many people were facing the issue, and Freddy K jumped in and helped almost everyone.
If you get the error below, you will probably use the URL below to open the web client.
http://<your container name>/BC
Since BcContainerHelper creates all sandbox images as multitenant, it is a must that you need to specify the “tenant” as default. Once you specify the tenant, you can log in to BC through the web client without any issue. Below is how the URL should be:
http://<your container name>/BC/SignIn?tenant=default
If you want to read more about it, you can refer to the GitHub issue: https://github.com/microsoft/navcontainerhelper/issues/1601
Thank you and Regards,
