ConnectionError: All APIs are unreachable about bitcash

[merc1er]

A program I develop based on BitCash worked without issues since the last days.

I started to get a ConnectionError every time I tried to broadcast a tx: "Transaction broadcast failed or unspends were already used". Now, all APIs are unreachable. I don't use any custom API, does BitCash use rest1.biggestfan.net as default? Is it giving troubles to anyone else?

EDIT: Despite the "All APIs are unreachable" error message, the script is working and txs are being broadcasted.

Yes I'm having the same issue. Will reach out to BiggestFan.

Just to leave some more info, reading the docs it seems that BitCash uses BitPay API. Browsing https://bitpay.com/insight/#/ALL/mainnet/home I found that a 429 error is raised for BCH and many other networks:
Error 429: Http failure response for https://api.bitcore.io/api/BCH/mainnet/block?limit=5: 429 Too Many Requests

Nvm, I've been reading the Python code and it seems that BitCash uses https://rest.bch.actorforth.org/v2/ as first option by default. I tried sending a raw transaction using their web interface and it worked. The raw tx was constructed from BitCash, so it's the broadcasting the failing point. I always broadcast the tx this way:
NetworkAPI.broadcast_tx(my_tx)

BitPay is used to calculate the fiat rate.

Yes I tried sending transactions through the web interface directly and it worked. It also works if I query the UTXO, wait 1 second then broadcast the transaction.

I will try to write a script that reproduces the issue so I can investigate this with BiggestFan

I'm not sure if this is related or not, but I am getting the same error when trying to get_transactions().

If I switch to net='mainnet' in the Wallet constructor then it works.

@willcharlton could you submit a minimal reproducible example?

With that I would be able to investigate this issue further.

[merc1er]

This should be fixed.
