Now that we have gone through the causes of the said error message, let us get into the solutions that you can implement to get rid of the issue for good. The below solutions have been reported as working by other users so they are very likely to work for you too.
1. Disable Third-Party Antivirus
As it turns out, some of the third-party antivirus suites are overprotective and usually interrupt with connections that are being established with your system which often causes certain issues such as this one. This happens when your antivirus suite thinks that the connection being established is not safe and therefore often terminates it or meddles with it. To avoid this kind of behaviour, you will have to create exclusions on your antivirus suite for Rainbow Six Siege so that it is not scanned when you are mid-game.
Alternatively, a good and recommended method of completely omitting the indulgence of your antivirus suite would be to uninstall it from your system and then remove any remaining files. Doing so will completely remove the trace of the antivirus software on your system.
Here’s how to uninstall your antivirus software:
After you have done so, try joining a game again and see if the issue persists. If so, move on to the next solution.
2. Flush your DNS
As we have mentioned, your network configuration is very likely to be the cause of the issue. Your DNS settings are usually the culprit in this scenario. Therefore, to resolve the issue, you will have to flush your DNS and then see the issue persists. However, before doing this, we recommend verifying the integrity of game files so that you are sure that the issue is not because of missing or corrupted game files.
Once you have done that, you can move on to flushing your DNS. Doing this is very easy and can be done pretty quickly. You might have to do flush your DNS a few times before the issue is resolved as reported by a user who was facing the issue. To flush your DNS, please follow the below instructions:
Head to your game and see if the issue is still there.
3. Change your DNS Server
Another thing you can do is change your network settings to use a different DNS server. Certain ISPs block various connections due to which the users often face connectivity issues. The workaround here would be to configure your network to use a public, robust and private (in terms of privacy) DNS server other than the default one which is controlled by your Internet Service Provider.
For this purpose, there are various public DNS servers that you can use. However, we would recommend using the DNS server provided by Cloudflare due to its robust and privacy features. The IP is 188.8.131.52. To change your DNS server, please refer to the How to Change DNS in Windows 10 article published on our site that explains the said thing very thoroughly.
4. Forward Ports used by Rainbow Six Siege
If the above solutions have failed to resolve the issue for you, it can be due to the fact that the game is not able to establish a connection with the game server, hence the connectivity failure. To resolve this, you will have to manually forward the ports provided by Ubisoft on this page.
Port forwarding can be different depending on the router/modem you are using as well as the manufacturer. However, for the sake of reference, you can check how to forward ports for online gaming. You will just have to replace the ports with the ports provided by Ubisoft in the above-mentioned link.
