“Unfortunately something went wrong” with second participant in the room

Hi guys, I saw coupple of question of this issue, I wanted to give more details from jvb.log:
I have already installed Jitsi Meet in a Ubuntu 18.04, I am using my own certificate, the port 10000/udp is enable.
I checked the topics related to this message I tried to implement but still is not working:
This error “Unfortunately something went wrong” is happening when the second participant enter the room and after 10 second the sessions are expiring.
I tried to undertand the log and I see that both participants are using 10000/udp

I coping only the parts where the problem is happenning:
by the way: when the second participant enter act as server
both participants are in the same network

Please, can you help me?, I Will really appreciate it.

Hi @edzela, were you able to solve the above issue?

We recently did a straight forward quick install one a single Ubuntu 16.04 server, our server is not behind NAT. Group Calls and audio works for us, although we have a peculiar issue.

People from Saudi Arabia for instance, when they join form the jitsi mobile app on wifi or mobile data, it works without any issue. Same users when they try to joining from their laptops via chrome (same wifi or mobile data hotspot) the issue you mentions happen. The same user can join from safari on the same mac where chrome fails! We checked on multiple devices and this issue is consistent.

People joining from chrome, join the meeting and see the “Unfortunately something went wrong” message after a few seconds. At the same time, we had a group call with 9 members with video from multiple devices on all from India and it worked without a single issue.

below jvb.log when a person joins the meeting successfully
