I was installed OnlyOffice on my Fedora 22 Server using Docker. The installation was pretty smooth and OnlyOffice is running on my system. I can open OnlyOffice without problems.
But, every time I tried to upload a file or even open the sample file, I got an error.
Download Failed, etc.
How to fix this? Anybody knows?
Update: I fixed this error by disabling firewall
systemctl stop firewalld
And now my Onlyoffice works like a charm
