"I'm having troubles in viewing my Xeoma remotely. Server: Ubuntu 14.04, Xeoma 15.8.27. Client: Win 10, Xeoma 16.10.31"
Answer:
First of all, we always advise to use the latest version of Xeoma on both server and client side (if the license allows for it). In your case, it should be Xeoma 16.10.31 on both server and client.
Then, even if you can't use the latest version of Xeoma (due to license limitation or other), you are strongly advised to use the same version of Xeoma on both server and client, even if not the latest one. You can download the version you need from our History Of Changes page: http://felenasoft.com/xeoma/en/changes/
Most likely, the issue will be resolved with these simple steps.
