Nethereum Azure SmartContracts Ethereum C#

I'm wondering if anyone has experience with I'm having trouble with While integrating Nethereum into my .NET Core application for deploying smart contracts to Ethereum, I hit a wall with deployment on Azure. Specifically, the operation times out every time I attempt to deploy a contract. I have set the gas price and the gas limit according to the network's conditions, but the deployment consistently fails with the message: 'The operation has timed out'. Hereโ€™s the code Iโ€™m using for deployment: ```csharp var web3 = new Web3("https://your-ethereum-node-url"); string privateKey = "your-private-key"; var account = new Account(privateKey); web3.TransactionManager.DefaultAccount = account.Address; var contract = web3.Eth.GetContract(abi, contractAddress); var deploymentTransaction = contract.DeployTransaction(); var transactionHash = await web3.Eth.Transactions.SendTransaction.SendRequestAsync(deploymentTransaction); ``` Iโ€™ve tried adjusting the timeout settings like this: ```csharp web3.TransactionManager.UseLegacyAsDefault = true; web3.TransactionManager.DefaultGas = new HexBigInteger(3000000); ``` While debugging, I noticed that the Azure application logs show a performance warning when the deployment is initiated. Additionally, reducing the gas limit doesnโ€™t seem to help, and the network status appears stable when I check Etherscan. I wonder if this issue could be related to the connection between Azure and the Ethereum network, or perhaps an issue with my account's permissions. Has anyone faced similar issues, and what solutions did you find effective? My development environment is Linux. I'm coming from a different tech stack and learning C#. Any advice would be much appreciated.
