Unexpected socket error: 10013 [Solved]

[briank]

After upgrading from SecureCRT 7.2.1 to 7.2.3 under Windows 8.1 Update and Norton Internet Security 21.2.0.38, I was getting the error "Unexpected socket error: 10013" when attempting to connect to a remote host.

Inspired by the discussion at https://forums.vandyke.com/showthread.php?t=11256, I tried the following fix, which worked:

Under Norton Internet Security > Settings > Network > Smart Firewall > Program Rules > Configure, change the entry for SecureCRT Application from "Auto" to "Allow" and click Apply.
