Bridge troubleshooting
The Bridge will not start, the model is not detected, or Bimiq says not connected. Work through these in order.
Most Bridge problems are one of four things: it is not running, the tunnel is blocked, the plugin is not loaded, or the session went idle.
Start here
Is the Bridge actually running?
Look for the tray icon. It hides behind the overflow arrow more often than anyone expects. If it is not there, check Task Manager for BIMIQBridge.exe.
Does the tray icon show a connection?
If there is no tunnel, the problem is network, not Bimiq. Skip to the tunnel section.
Is the model open?
The plugins connect when a model is open. A running Bridge with Revit closed is a Bridge with nothing to read.
Restart the Bridge.
If the session has been idle a long time, restarting re-registers it. This resolves a genuine share of cases and costs ten seconds.
The Bridge will not start
| Symptom | Cause and fix |
|---|---|
| Nothing happens when you double-click it | An instance is already running. Check Task Manager, and look for the tray icon under the overflow arrow |
| A dialog says it is already running | Same thing. Dismiss it and find the tray icon |
| It crashes immediately | Install .NET Desktop Runtime 10.0 |
The tunnel will not open
| Symptom | Cause and fix |
|---|---|
| Tray icon shows no connection | Antivirus has blocked the tunnel executable. Add an exception for the Bridge's temporary folder |
| It works at home but not in the office | The corporate firewall is blocking outbound. Ask IT to allow *.trycloudflare.com on ports 443 and 7844 outbound |
| Tunnel starts but Bimiq still shows disconnected | Registration failed. Restart the Bridge, and if it persists, contact us |
Revit does not show the plugin
| Symptom | Cause and fix |
|---|---|
| No BIMIQ panel in the Add-Ins ribbon | The plugin was not installed for that Revit year. Right-click the tray icon and choose Install Revit Plugin |
| The panel is there but will not connect | The Bridge is not running. Start it |
| Revit reports a class or load error | The installed plugin does not match that Revit version. Reinstall from the tray icon so it picks the right build |
If you need to confirm what Revit did with the add-in, its journal files are under %LOCALAPPDATA%\Autodesk\Revit\Autodesk Revit {year}\Journals\.
Navisworks does not show the plugin
Check the edition first. Navisworks Manage supports plugins. Simulate and Freedom do not, and no amount of reinstalling will change that.
If you do have Manage, reinstall the plugin from the tray icon.
Bimiq says the Bridge is not connected
Work down this list:
- Is
BIMIQBridge.exein Task Manager? - Has it been idle more than 15 minutes? Sessions expire. Restart it.
- Is the tunnel up? The tray icon tells you.
- Is a model open in Revit or Navisworks?
A request times out
Long operations on a large model can exceed the request timeout.
| Cause | What to do |
|---|---|
| Revit is syncing with central | Wait for the sync to finish, then retry. Revit will not answer while it is syncing |
| The model is very large | Narrow the request. Filter by category or level rather than asking for everything |
| The plugin stopped responding | Reload the model in Revit or Navisworks |
Still stuck
Tell us what the tray icon shows, which Revit or Navisworks version you are on, and what you were running when it failed. Reach us from the contact page.
