## How can I specify connection port for Keyserver?

Add a new Keyserver (or modify existing one) by going to Preferences -> General -> Keyservers. Enter the port number after the Keyserver address and preceded it by a colon. For example, "p80.pool.sks-keyservers.net:80" (without quotation marks) means that server "p80.pool.sks-keyservers.net" is working on a port 80.

Default connection port is 11371 and it doesn't need to be specified.

## A wrong primary user id is shown when searching on a Keyserver

Unfortunately, this is a bug in the SKS Keyserver software. Its machine-readable output returns the user ids in an arbitrary order. Read the related bug report for more information.
