2. What operating system and processor architecture are you using?
   Windows server 2019

3. What version of .NET framework are you using?
   .net framework 4.8

4. What did you do?
   Started seeing this error on the server since few days, was working before -
   Error: Snowflake Internal Error: Unable to connect. One or more errors occurred. SqlState: 08006, VendorCode: 270001, QueryId:
   at Snowflake.Data.Core.Session.SessionPool.NewSession(String connectionString, SecureString password)
   at Snowflake.Data.Core.Session.SessionPool.GetSession(String connStr, SecureString password)
   at Snowflake.Data.Client.SnowflakeDbConnection.Open()

5. What did you expect to see?
   No error on Snowflake connection.
   What should have happened and what happened instead?

6. Can you set logging to DEBUG and collect the logs?
   snowflake_dotnet4-Arw - Copy.log

   https://community.snowflake.com/s/article/How-to-generate-log-file-on-Snowflake-connectors

   There is an example in READMD.md file showing you how to enable logging.

7. What is your Snowflake account identifier, if any? (Optional)

hi - thanks for sharing the logs. they suggest the client driver is not able to connect to the Snowflake account due to the login request not getting a response and eventually timing out.

this behaviour is very rarely associated with the driver itself, especially if the same workflow was working with the same driver earlier, and suddenly it stopped working.
this suggests a change in the underlying network configuration which now apparently prevents the client from reaching the server.

you can use https://community.snowflake.com/s/article/Snowflake-Client-Connectivity-Troubleshooting for generic connectivity troubleshooting guide, or if you prefer to work with someone from Snowflake on that, please open a Support ticket with us - this repository focuses on the .NET driver and issues/requests associated with the .NET driver. This problem you're seeing is not related to that.

for now I'm closing this Issue as it is not related to the .NET driver but if you think it is afterwards, please do comment and attach the relevant evidence and I can continue looking.
