I still haven't found a way to completely fix this, but I have two easy work-arounds in the comments which should be elevated to "answers".
(1) Access the console with a browser at the address "localhost:port/ibm/console". The port number can be found as follows:
a. After starting your server, in the Servers view, right-click on the server and select "Properties"
b. In the left pane, click "WebSphere Application Server".
c. Click "Open SystemOut.log in editor.
d. In the SystemOut.log, search for the word "adminconsole". You should find a line that ends in something like this: Web Module adminconsole redirector has been bound to admin_host[:9068,:9051]. The port numbers might be different. Note the first port number listed in this line. This is the port number you should try for getting to your Admin Console using the URL.
(2) Create a new workspace. In my experience, the problem will not be occurring in the new workspace.
http://localhost:port/ibm/console
. Since looks like you have 3 WAS profiles, the port will be probably 9062 (but you can check it in the logs or try 60 and 61). – Larger
