Unfortunately, we don't provide our software for testing privately. However, we will provide a beta version of Host/Agent for Mac/Linux for open testing - it will be publicly available on our website for everyone to download, test and provide feedback (pretty much like with Viewer for Linux/Mac).
I've checked with our development department on the ETA for the address book availability in the mobile Viewer and an approximate ETA for it is currently within summer/fall this year. We'll do our best to make it available as soon as we can.
We apologize for keeping everyone waiting for so long. Unfortunately, there were some delays in the release due to the fact that we've decided to use more advanced framework (which has made the development process longer, but will ultimately make the product better and more reliable). I've checked with our developers and, according to them, we plan to release a first test version of Host for Mac/Linux in a few weeks and a final stable version of Viewer for Mac/Linux by the end of this year.
Could you please send us the most recent Host logs fr om the remote machines wh ere the issue occurs? You can locate the log files in the following folder: C:\Program Files (x86)\Remote Utilities - Host\Logs\ and send them to firstname.lastname@example.org for examination.
This is to inform you that our developers have let me know that, unfortunately, due to the issues with our monitoring service we haven't received a notification about connectivity issues with our servers in a timely manner and, therefore, a simple issue was resolved much later than it could be fixed if we would've find out about it right away (and would've fixed it in just a couple of minutes). We apologize for the inconvenience.
We’re glad to hear that the connection is working for you now and you’re able to connect to your Hosts. As for what caused the issue in the first place - our developers are currently investigating this. I will let you know as soon as there are any updates on this from our devs.
Please let us know if you have more questions or if the issue still persists for you.
