<summary><strong>Bot instantly closes after trying to open it</strong></summary>

Make sure to have your ip authorized as said at the beginning of the guide, and also that it is the correct one!

If that doesn't work, try this:

Go to Start > Settings > Update & Security > Windows Security > Virus & threat protection. Under Virus & threat protection settings, select Manage settings, and then under Exclusions, select Add or remove exclusions. Select Add an [exclusion](https://support.microsoft.com/en-us/windows/add-an-exclusion-to-windows-security-811816c0-4dfd-af4a-47e4-c301afe13b26), and then select from files, folders, file types, or process.

Also try this:

* sync windows time, if no button to sync turn off and turn on again automatic time
* disable ipv6 on server/local: <https://support.nordvpn.com/hc/en-us/articles/19919186892305-How-to-disable-IPv6-on-Windows>

Also try to disable real-time protection on windows security!

* before adding wallets or positions, make sure to set the node in settings first

<summary><strong>Why do my bundles keep getting rejected?</strong></summary>

Check logs, if you have this message it means that Jito has banned your private key.

<summary><strong>Why does it say "Transaction Sent 0/XX" but in reallity it has not sent any tx?</strong></summary>

It's cause by the field called "Transaction Request Timeout" that you can find in general settings.

If your node has low TPS (<1000) you should set a number higher than 800 (but make sure to make a couple of tests to find the right compromise); if you have a much more efficient node you can use a lower value for that field.
