Constantly getting 'transaction validity period exceeded' and other errors

Describe the bug I've tried implementing solana-swap into my code (I'm using vite server with electron front end). Initially, I was getting CORS errors from your https://swap.solxtence.com environment, so I've intercepted the requests so they go through a proxy handler, which works fine.

Now, I've tried through Quicknodes and Alchemy (I gave up on the public RPC, as it's immediately rate limited) and I'm getting the following errors about 95% of the time, with the occasional trades going through (my full logs for 1 tx is below - note that the failure often happens in under 1 sec, sorry I didn't add timestamps).

I've tried increasing the transaction validity period and number of retries, but it achieves nothing.

I've tried increasing the transaction validity period and number of retries, but it achieves nothing. The relevant code is at the bottom of this issue.
