Sql-server – Unable to connect to Listener after rebuild

I dropped an AG with

DROP AVAILABILITY GROUP [MyDb] 

it had a listener.

I left the listener open in the object Explorer of SSMS 17.3. While the AG and Listener were down. I hit refresh on the listener a couple times in SSMS. (because I have OCD and had to make sure it was gone)

I recreated the AG with the same listener and when I hit refresh it would not connect. I get the message below. I tried the following and was not able to connect, receiving the same error.

• Disconnect the listener in 17.3 and try to create a fresh connection
• Open SSMS 16 (13.0.15900.1) and try and connect
• Close and reopen both SSMS sessions.
• Try adding MultiSubnetFailover=True to the Additional Connection Parameters tab of the connect popup (this a multi-subnet listener)

I was able to connect using the fully qualified domain name 'MyListener.fully.domain.net', but was still unable to connect with just 'MyListener'

A coworker was able to connect to the listener without issue, using both 'MyListener' and 'MyListener.fully.domain.net'

I rebooted my Windows 10 PC, and after reopening SSMS I was able to connect with just the listener name 'MyListener'.

I upgraded SSMS to 17.4 and the same thing happens.

What is happening here? How can clear the issue without rebooting my PC?

Note in all cases I created the AG and added the listener using a variation of the T-SQL from https://www.brentozar.com/archive/2016/06/sql-server-2016-availability-groups-direct-seeding/ The AG is on an instance running SQL Server 2016 RTM, the database is AdventureWorks2014.
