Add RPC fallback verification to fix connection failures while calling if web3.is_connected()on Gensyn Testnet

[xailong-6969]

Adds fallback connection verification to handle cases where the standard connection check may return false on certain RPC provider configurations, ensuring more reliable connectivity to the Gensyn Testnet.

so i am attaching the main error log here:

When connecting to Gensyn Testnet using the official public RPC endpoint (https://gensyn-testnet.g.alchemy.com/public), the web3.is_connected() method returns False due to restricted web3_clientVersion access, causing the connection to fail even though the blockchain is fully accessible.

Reference: rl-swarm-contracts deployment config

Solution

Added a fallback verification in genrl/blockchain/connections.py that uses eth.block_number when web3.is_connected() fails.

The log demonstrates:

• web3_clientVersion fails with HTTP 401
• Fallback eth_blockNumber query succeeds
• Connection established successfully to Gensyn Testnet

i am attching here the screenshot of swarm_launcher.log after running the node with block_number method through the contract endpoint directly:

@jcd496 kindly look into this issue.

this is a great fix @xailong-6969 . We are working on a solution to the RPC issues right now. Depending on the outcome of the RPC solution, we may merge this as well. thanks!
