When an error happens, it is necessary for us to figure out additional information about the network requests in your browser while an issue. Short.io service team may request you to record a HAR file, or a log of network requests, while that issue is occurring and then send it to the Short.io team for discovering the error.

Note: HAR files contain sensitive data, including content of the pages you downloaded while recording and your cookies. This allows anyone with the HAR file to impersonate your account and all the information that you submitted while recording (personal details, passwords, credit card numbers, etc.).

Below are some instructions about how you can easily generate a HAR file using different browsers.
