## You are experiencing one of the following issues

* I am having trouble installing or opening the Postman desktop app.
* I see a modal displaying the error " *Could not open Postman"* .
* I am having trouble opening a request in a new tab.
* I am stuck in a “session expired” loop.

## How to unblock yourself

1. To help isolate the issue, try using the [Postman web app](https://go.postman.co) in your browser. If that works, it indicates a possible client-side issue with the Postman desktop app.

* If the issue occurs only in the Postman desktop app, go to step 2 and remove your local data.
* If the issue occurs in both the Postman desktop and web app, then [submit a support request](https://support.postman.com/hc/en-us/requests/new/) .

2. [Remove Postman’s local data](/help/faqs/troubleshooting/how-to-remove-local-data) .

## Submit a support request

If you’re still experiencing this issue after removing your local data or if you can replicate the problem on both the Postman web and desktop apps, [submit a support request](https://support.postman.com/hc/en-us/requests/new/) with the following information:

* A screenshot of the error
* A copy of your [app logs](/help/faqs/troubleshooting/how-to-get-logs-from-the-postman-desktop-app)
