Link to download file and when clicking download button still say "send.example.com" even though I set BASE_URL to my base URL

I installed Send and the installation went fine and the page itself works fine, and when I upload a file it works fine, but there is a problem with the URLs. I added the environment variable BASE_URL to https://send.mydomain.com (I am running Send using Docker). When the file is done uploading, the link it gives me to share the file is https://send.example.com/download/[long string of letters and numbers] instead of https://send.mydomain.com/download/[long string of letters and numbers]
But even if I copy the link and change example.com to mydomain.com, and visit that URL, sure it brings me to the page to download the files, but it's annoying to have to change that in every link. Interestingly, when I click the "send" logo in the top left corner of the screen is does bring me back to the Send main page with the correct base URL, but this base URL doesn't show in the download links it generates.

Just set DETECT_BASE_URL=true, then it will be ok
