QVS Tunnel Error

jeremy_fourman — Mon, 26 Jan 2026 18:19:17 GMT

Hi all,

Sorry to keep whipping this dead horse but I am kinda stuck here. I am receiving the QVSTunnel.dll error that usually indicates either

a. tunnel is not installed/setyp on the webserver

b. Link Machine Name needs entered.

c. Config.xml wasn't updated

However all of those are configured. I can execute the tunnel test and get a proper success message, from inside and outside the firewall. I have the fqdn name entered into the Link Machine Name, I have checked config.xml and this has the subdomain.domain.com entered as well.

but nothing is seeming to work when using the plugin.

qvp://subdomain.domain.com/Published/test.qvw?iis_authenticate=stuff&tunneler=http%3A//subdomain.domain.com/scripts/QVSTunnel.dll%3Fhost%3Dqvs could not be opened

This is a distributed installation with the QVWS in a DMZ using IIS. All other services are installed within the protected network. There is a hosts file on the webserver that resolves the QVS server name. Both servers can resolve subdomain.domain.com and everything has generally been easy going until this. As a matter of fact this is the last item to check off of the setup list.

What am I missing? Please let me know if you need more information.

Thanks,

-Jeremy

If I enter the internal IP of the QVS server within the Link Machine Name, then the users on LAN are able to use the IE plugin. What can I do for the external users?

Hi Alice - This particular issue was resolved via QT Support. We were using Certificates for Trust and there was a bug fixed in QV 11,2 SR3 around this but in the meantime they had to do a registry setting adjustment. I would suggest opening a ticket with QT to get it resolved quicker.

Hope it works out for you.

Thank you Jeremy! This particular error was resolved by their IT-department, and I have not yet found out how. I will try to get that info and return here with it. Speaking of whipping old horses. 😃

Hi,

I am sure they had to NAT port 4747 to the internal server.

You can also set the link machine name to (FromRequest) with parentheses.
