What is TCP Override?
Does your connection appear ‘broken’ a few minutes after enabling TunnelBear, or is streaming slow and choppy? It may be that your ISP (internet service provider) is throttling or even blocking UDP traffic. Alternatively, your ISP might be experiencing some technical difficulties; in which case enabling this feature can help.
TCP Override is an advanced setting available on our macOS and Windows desktop apps only. TCP Override forces TunnelBear to use a slightly slower, but more reliable protocol (TCP instead of UDP). This might result in better performance on an unreliable connection.
Troubleshooting issues with TCP Override
If you find that TCP Override decreases the performance of your Bear, then it’s likely that you don’t need it; in this circumstance we recommend that you disable the feature. We also advise that you check out the following help articles if you are having a connection issue, or if your are having any speed issues.
