Deploying my GCP .NET Core app causes a 500 error when connecting to SQL Server, unlike local execution. Below is an example exception:
throw new DataProvider.ConnectionError("TCP Error: Unable to access SQL instance. Verify instance name and remote settings.");
The error likely stems from differences in network configuration between your local environment and the GCP deployment. In many cases, the IP address or firewall settings may block access to the SQL Server instance. It is important to confirm that the SQL Server allows connections from the public IP range used by your GCP environment. Additionally, checking the connection string for any discrepancies that might affect instance resolution can be beneficial. I encountered similar issues and resolved them by updating firewall rules and verifying network settings in the cloud configuration.
hey, im thinkin that its a config issue in the gcp env. your sql may be blocking remote calls. rough experiments showed me that resetting allowed ips in sql config helped. good luck!
hey, im wonderin if maybe your connection creds or network settings got mixed up on gcp? did u double-check if all env variabl settings match between local and cloud? any other quirks in your deploy setup?
hey, maybe your gcp outbout settings are messing things up. i had a simlar problem and adjusting firewall rules on the cloud fixed it. give that a try, might resolve your 500 error issue.
In my experience, issues like these can sometimes be resolved by auditing the network configuration on both ends more comprehensively. I encountered a similar problem where SQL Server connectivity worked locally but failed on a cloud deployment. After thorough investigation, I found that advanced network policies on the cloud side were blocking certain types of encrypted traffic. Adjusting security protocols and ensuring that both SSL checks and encryption settings were correctly configured helped resolve the connectivity issue. It is also beneficial to review any intermediary network appliances or proxies that might intercept or modify the traffic.
