When attempting to connect to the Technolutions SFTP, it's important to use the Connection Validation Tool.

If your problem persists, confirm the following common issues aren't at play:

1. Changes to User IDs in Slate may take up to 1 hour to populate throughout the system: If the change was made and the query immediately exported on demand, the query may not have recognized the username.

2. Be sure the corresponding public key is installed on the remote server for this User ID:  Some users find it helpful to test the connection using a username and password to rule out an issue with the public key pair. 

3. Double check key itself: does it match the key on the remote server for this User ID?

4. If you are using a keypair, it must be an RSA key: It must also include the following comments around the key itself:

   -----BEGIN RSA PRIVATE KEY-----

   Followed by the key, then:

   -----END RSA PRIVATE KEY-----

5. Check your firewall: Are Slate's connections allowed? Outbound connections from Slate are initiated from the IP addresses listed in the Outbound Networks article should be included in your firewall whitelist.

6. Check your Allowed Networks: Is your external IP address listed in the Allowed Networks field for the service account? 

7. Parallel test: Ensure that you can hit the path via a parallel test from a different service, such as Filezilla or WinSCP.  If you can access the path from the third party service, your credentials are probably correct—meaning something is misconfigured in your original tool.

8.  Check the IP Threat List:  Slate uses BrightCloud Threat Intelligence to identify and block IP addresses at our firewall that have a low reputation/high risk and that may be a threat.  Use the BrightCloud IP address search to check the reputation of the IP address.  If the address is found to have a high risk, then it is being blocked.
   

   

   
   If the IP address is being blocked, you will need to work with your ISP to remove the High Risk status for the IP address. You can also submit a request to change the IP threat status through BrightCloud.
