Problem accessing /grid/register

[AJCastello]

HI, i've finished the whole installation and it was really smooth and clean. But i don't know what i'am doing wrong and i cant register the session and even try the example.php.

After 'all green' running on Docker, accessing the log file, this is the first exception:

... selenium-hub_1 | 02:56:29.065 INFO [Hub.start] - Selenium Grid hub is up and running selenium-hub_1 | 02:56:29.067 INFO [Hub.start] - Nodes should register to http://172.24.0.2:4444/grid/register/ selenium-hub_1 | 02:56:29.067 INFO [Hub.start] - Clients should connect to http://172.24.0.2:4444/wd/hub selenium-hub_1 | 2020-07-19 02:56:31.038:WARN:osjs.HttpChannel:qtp811587677-10: /grid/register selenium-hub_1 | java.lang.NullPointerException selenium-hub_1 | at java.util.TreeMap.rotateLeft(TreeMap.java:2226) selenium-hub_1 | at java.util.TreeMap.fixAfterInsertion(TreeMap.java:2291) selenium-hub_1 | at java.util.TreeMap.put(TreeMap.java:582) ...

continue a long exceptions list, then this:

... selenium-hub_1 | at java.lang.Thread.run(Thread.java:748) selenium-hub_1 | 02:56:31.070 INFO [DefaultGridRegistry.add] - Registered a node http://172.24.0.4:5555 selenium-hub_1 | 02:56:36.211 INFO [DefaultGridRegistry.add] - Registered a node http://172.24.0.3:5555 selenium-hub_1 | 2020-07-19 03:08:19.701:WARN:osjs.HttpChannel:qtp811587677-15: /grid/register/ selenium-hub_1 | org.openqa.selenium.json.JsonException: Expected to read a START_MAP but instead have: END.

and the list goes on.

About the environment Trying to access by the IP given on the console(like: http://172.24.0.2:4444/) doesn't load a page, gives ERR_CONNECTION_TIMED_OUT

So i try localhost http://localhost:4444/grid/console - shows chrome and firefox webdrivers working fine

Accessing http://localhost:4444/grid/register, gives:

HTTP ERROR 500 Problem accessing /grid/register. Reason:

Hi,

I just saw your issue today. I did several refactors on the project and in documentation, can you test again?
