Server Error - Management Console

[JLSeagull]

Hello Team!

I am facing this problem to log in 3CX Managment Console. "Server Error message".

Information: 3CX Phone System running on AWS Cloud - Platform: Debian GNU-Linux 9 Stretch.

Scenario: Yesterday at night, 2020/05/14, everything was green on dashboard. I decided to create the outbound rules for remote 3CX Apps, according to the link https://www.3cx.com/docs/manual/firewall-router-configuration., as I had only Inbound Rules. So, I configured the Ports 443 (outbound, TCP) for Google Android Push and 2195, 2196 (outbound, TCP) for Apple iOS Push. Then I logged in 3CX Phone System Management Console to run a Firewall test checker. My problems started here. Only stun has passed successful.

What I did: well, once firewall was failing I deleted all Outbound Rules created on my AWS EC2 instance and repeated the Firewall test checker. Same problem: everything was failing. I've restarted all 3CX Services via 3CX Management Console. Same problem with the firewall.

Issues: suddenly I couldn't log in 3CX Management Console anymore. The page spends some time loading and shows up the error message "Server Error".

What I did:

1. I've tried to log in 3CX Management Console in other computer. Same error. I've tried in laptops running Windows and Linux. Same error.

I'm able to connect my AWS EC2 intance, via EC2 Management Console, so I've:

1. verified if something was wrong with AWS EC2 Instance: everything was running fine.
2. stopped and started the EC2 instance. Same "Server Error".
3. rebooted my EC2 instance. Same "Server Error".

I'm able to connect my AWS EC2 Instance via SSH, so I've:

1. verified the 3CX Services:

sudo service 3CX* status

3CXEventNotificationManager.service - active (running)
3CXCfgServ01.service - active (running)
3CXMediaServer.service - active (running)
3CXPhoneSystemMC01.service - active (running)
3CXPhoneSystem01.service - active (running)
3CXIVR01.service - active (running)
3CXQueueManager01.service - active (running)
3CXCallFlow01.service - active (running)
3CXSystemService01.service - active (running)
3CXTunnel01.service - active (running)
3CXAudioProvider01.service - active (running)
3CXHotelModule01.service - status not displayed

2. Stopped and restarted all 3CX Services. Same status as displayed above (point 3.). Same "Server Error".
3. Rebooted the 3CX Phone System. Same "Server Error".

What I noticed:

1. Apparently all phones and extensions are working fine.
2. SINCE YESTERDAY (2020/05/14) I don't receive e-mail notification from 3CX Phone System. The last one was in Thu, May 14, 2:18 PM (1 day ago) about Stopped Services Notification.
3. TODAY (2020/05/15) I didn't receive Web Meeting Reports, even holding at least six videoconferences - I DON'T KNOW IF THIS IS CONNECTED WITH THE "SERVER ERROR" ON 3CX MANAGEMENT CONSOLE.
4. Participants complained about not receiving invitation emails from 3CX Webmeeting - I DON'T KNOW IF THIS IS CONNECTED WITH THE "SERVER ERROR" ON 3CX MANAGEMENT CONSOLE.


Every help is welcome!

No idea why you decided to create firewall rules when everything was already green. To recover, I'd say roll back your snapshot but I'm guessing you didn't make one. So take one now, then SSH in and take a backup (or if you have scheduled backups running then grab the latest one):

https://www.3cx.com/docs/backup-restore-command-line/

Save the backup outside of the 3CX path (and maybe copy it off the box just in case) and then uninstall 3CX and reinstall it:

https://www.3cx.com/community/threads/how-do-i-uninstall-3cx-on-linux-to-restore-backup.46572/

Or just take your backup, copy if off the instance, delete it and recreate it.

Hi, @cobaltit ! Thank you again for your reply.

Well, my idea was put all my rules, inbound and outbound, according to the 3Cx's guidelines. In fact I didn't make a snapshot, but I have one available now. But, before, following your suggestion, I've took my scheduled backup, copied it off my instance and recreated my 3CX Phone System via SSH using /usr/sbin/3CXCleanup after /usr/sbin/3CXWizard (I had to do this step twice, because at first time I got the same "server error" after to execute FW Checker and it fail again). And I only could recreate it after create an outbound rule to allow connection to the activation.3cx.com.

What is happening now:

My 3CX Phone System's firewall just get green if it's allowed all traffic inbound and outbound. It fail always I try associate my instance to my original security group with default 3CX ports.

My questions:

1. Why is my firewall suddenly behaving this way? Note: I didn't changed my original inbound rules.
2. Why was the SMTP server impacted (I am using 3CX SMTP Server)?
