[QA] Sometimes transaction fails with "BlockhashNotFound" error

[tsadovska]

Describe the current behavior in detail

Checked on https://preview.portalbridge.com/712d941311/.

Steps:

1. Prepare to send 0.354203 USDC from Solana (Phantom) to Sui (Sui wallet)
2. Click on "Review transaction" button
3. Click on "Confirm transaction" button

Actual result: Phantom notification does not appear. Error "BlockhashNotFound" is displayed in Console. Expected result: Phantom notification appears and transaction continues without error.

What is the expected/desired behavior

Noticed 3 times during the day. Phantom notification appears after clicking on "Confirm transaction" button again.
