OK

it turns out the problem is NOT in OM plugin and NOT in OM
It is increased browser security (as usual)

To fix it and made Moodle integration work again please do the following:
1) stop OM
2) edit ${OM_HOME}/conf/context.xml
      add <CookieProcessor sameSiteCookies="none"/> BEFORE </Context>
3) start OM

I guess it should be documented somewhere
I would appreciate if you can suggest good place for it :))

Subject: Re: Invalid Hash Access denied. You have no rights to enter this room.

Hello,

I'm going to release next version of Moodle plugin this week
But since you are able to enter the room using some browsers I doubt
it will help
Is it possible you have multiple Tabs/Windows with OM in the same
browser simultaneously?

I had problem with moodle plugin in OM 5.0.0 , because when i tried to access 
classroom from Chrome browser it said Invalid Hash Access denied. You have no 
rights to enter this room. I didn't have problem entering classroom directly 
from server page only from moodle plugin and i had to use Opera browser because 
it worked best. Now i installed OM 5.0.1 and when i try to enter through moodle 
plugin with Opera the same error occurs like with Chrome Invalid Hash Access 
denied. You have no rights to enter this room. Now only Firefox and Edge 
browsers are working. I checked everything and i have latest openmeetings 
plugin for moodle installed and yes i only open one tab at time but i am sure 
that problem is with the plugin because i don't have that problem when i enter 
OM directly.
