Companion integration- uploading not working in some of environments

Hello all,

I have uppy/companion working on a number of environments successfully, but i have a number not working with the same configuration.

with the ones that don’t work with the companion integration
uppy uploads from “my devices” successully
with an companion integration e.g. dropbox, it autheniates ok and you can see the files in the uploader, but when you upload, it doesn’t transfer to TUSD to upload the files - nothing in the tusd logs
see below logs

above the dark red line is the environment when it doesn’t upload the file

below the red line is another environment that is successfull

Any ideas?
