Error while downloading the document file to be converted

I take that back… I can’t get this error to go away… I managed to fix it on a test machine… but I can’t get it to work on out production nextcloud… Any ideas?

I can also add that I have 2 identical Nextclouds that I want to connect to the same Onlyoffice… 1 of them can connect, but the other one cannot.

Production Nextcloud:

Test server 1: (Works)

Test server 2: (Dosen’t work)

Yes… Our production is on NC16. Yes it is another address to the production server, but that onlyoffice is a direct copy of the other onlyoffice with a changed ip.
