Has anyone faced a "Network transport failure" while trying to set up a direct connection to snowflake?

I am trying to make a direct connection to snowflake in data connection and get the following error:


The explorer command failed to run:
java.lang.Throwable:Network transport failure
com.palantir.conjure.java.dialogue.serde.DefaultClients.block(DefaultClients.java:142)

Does anyone have any ideas on how to resolve? Thanks!

It is likely that the list of egress policies you have on the source are either not sufficient for your snowflake connection, or are not allowlisted correctly. You should be able to find full stacktrace of the error if you look into the “logs” tab on the source. Please file a support ticket if you continue to run into this issue and the logs are not indicative.

Echoing what @sshukla said. Errors like this are often the result of egress issues. Can you verify that you’ve followed these instructions:

Yes, using the system allowlist command, we were able to see all egress policies needed and made a successful connection. thanks!
