Can’t connect to Hosted – Error: Remote Desktop Gateway temporarily unavailable

“Your computer can’t connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable. Try reconnecting later or contact your network administrator for assistance.”

This error is usually related to internet connectivity on the workstation, a profile reset for the user will not resolve the error.

Test the internet connection, i.e. try and access and see if the page loads.

If you can, try and browse to the following gateway addresses in your web browser (Internet Explorer, not Chrome), you should see the Scomis logo appear for each one.


If you can access each or only some of the webpages above, check the webpage certificate to see if it is issued by QuoVadis (Click the padlock icon). If it is issued by another provider i.e. SmoothWall, the filtering system or proxy may be intercepting this and you will need to ask your IT team to add an exception. If none of the web pages are accessible, try pinging them. If there is no response, it is likely the be an internet/filtering/proxy related issue specific to the workstation, especially if no other users in the school are experiencing the same issue. See the Hosted Applications internet requirements here.

You can also try:

In the Scomis Hosted connector click the Help > Reset to default settings option

In the Scomis Hosted connector click the Connections > Force failover connection option. This will only work if you are able to access one of the gateway addresses above, as this will move your connection to an alternative one than the default.

Although unlikley to be a user account related issue, try logging onto another workstation with the same user account and vice versa, by logging onto the affected workstation with a different user account.

If the user cannot log onto any workstation and receives the same error, it may be that the temporary password that was originally set has expired and will need to be reset. If resettting the password does not work, on the machine, remove all entries of Scomis addresses from ‘Credentials Manager‘ as an old password could be saved here that the connector is trying to use.

Please note, if this is a Home/Personal PC, Scomis are unable to provide support.
