Appdev commented on OPENMEETINGS-2224:
--------------------------------------
I tried to change the locahost to the IPv6 specification. It didn't work. I
should point out a few things I noticed.
1) Prior to this I had changed the default ports for OM from \{5080, 5443} to
\{80, 443} because some ISPs block access to those higher ports making the
installation unavailable to users in certain locations. (This problem we are
dealing with existed BEFORE that change was made.)
2) When I change the applicationContext file, the installation refers back to
the higher port (5443) in spite of the previous change in the configuration of
OM.
3) After making the changes I could not reach the application. I then ran the
netstat query below. Please see the echo. Let me know if this provides some
insight. It appears that if we restrict the Java infrastructure to IPv4 then
this issue will be resolved. OR we force the application to listen to the
appropriate IPv6 port. Please advise on exact syntax to make sure we are
getting it right. Thanks.

> Hi:
> I notice this issue has been discussed in a number of previous threads but I
> do not see a resolution in those threads. Sorry to have to open this up
> again. I have installed OM5.0.0-M3 on Centos7. I followed the
> [instructions|https://cwiki.apache.org/confluence/download/attachments/27838216/Installation%20OpenMeetings%205.0.0-M3%20on%20Centos%207.pdf?version=3&modificationDate=1579175324000&api=v2]
> and the process completed "successfully". I was able to log into the
> application and effect the customizations. No problem there.
> KMS is running. (I have started, stopped and restarted it to confirm it is
> running.) I have changed permissions on the OM files to the user account.
> 1) However, when I start a conferencing session I get "Multimedia Server Is
> Inaccessible". There are usually several warnings at once indicating that
> several processes are failing. (You can go through the setup of a conference
> but once you enter a room, that failure occurs, and does so frequently during
> a session.)
> 2) Also I am unable to get the video feed of ANY participants in a
> conferencing session to work.
> Please assist on how to resolve this. Clearly this is an issue with KMS but
> it's unclear how to proceed.
> Thanks.
