I am unable to use Studio web due to error “Could not connect to SignalR”.
Due to this I cannot run any process in studio web.
Please find the screenshot attached.
How to resolve this issue ?
Hi @reshma.mohan,
Verify Firewall and Proxy Settings
Server Configuration: If you’re hosting the server, ensure SignalR services are correctly configured and running.
Else please contact UiPath support team

The “Could not connect to SignalR” error in UiPath Studio Web typically occurs when there is a connectivity issue between UiPath Studio Web and the orchestrator, which uses SignalR to communicate between components. To resolve this issue, here are some steps you can follow:
- Check Network and Firewall Settings
- Ensure your network is stable and that there are no restrictions that could block the communication between UiPath Studio Web and the Orchestrator.
- SignalR communication may be blocked by firewalls, proxies, or other network security measures. Ensure that ports required by UiPath are open.
- Make sure that
443(HTTPS port) is open for communication between the Studio and the Orchestrator.
- Verify Orchestrator URL
- Ensure that the Orchestrator URL configured in your UiPath Studio Web is correct. If you’re using a cloud Orchestrator, make sure the URL matches exactly.
- If you’re using a private Orchestrator, ensure it’s accessible.
- Clear Browser Cache
- Sometimes, browser cache can cause issues with connectivity. Clear your browser cache and try again.
- Alternatively, try opening UiPath Studio Web in a different browser to see if the issue persists.
Hi @reshma.mohan !
As mentioned in this thread, the issue is likely related to your firewall, VPN or proxy rules.
Your document mentioned the domain access required by Studio Web:
