Having issues getting FTPS server load balanced
We had the same issue as this link FTPS Load-balancing Problem | DevCentral (f5.com) Then our issue was resolved using this linkConfiguring passthrough FTPS load balancing (f5.com) This worked for a period of time and now our issues are back and its intermittently. Ports are not using the enforced port range on F5 and we are getting these errors below when trying to connect with FTPS port 21 and 990 going through F5. Using Move it Automation and when using winscp to connect. Any help would be greatly appreciated! Using move it automation Could not list directory: The connection timed-out.
