Server Error on the 3CX Management Console

[ArcSupport]

When I try to log into the management console, I get the message Server Error. I can access the server (through SSH and locally) and the phones all seem to work correctly.


What I have done to try to resolve the problem:

• Restart the server
• Updated 3CX
• Verified the Firewall configuration
• Went through the logs

I unfornately don’t have any experience with 3CX servers. Could someone give me pointers where I could look to find a way to solve the problem?

To first get a better understanding of your setup:

1. Where is this 3CX Instance located, is it Hosted and with who, is it on-prem?
2. How was this 3CX Instance deployed, via the Partner Portal, Hosting provider's marketplace or via the 3CX ISO?
3. What exact version 3CX are you running?
4. Did the issue occur right after any specific actions?
5. When you SSH to the machine, have you happened to check what 3CX services are running?

You can check with:

service 3CX* status

Try starting stopped services with:

service <Service_Name> start

Example: service 3CXPhoneSystemMC01 start

Note: For the commands use sudo if necessary.

Thank you for your answer.

1. The 3CX Instance is on-prem
2. I think it was deployed using the 3CX ISO, but I don't know for sure because I am not the one who deployed it and there is absolutely no documentation.
3. When I run the command apt-cache policy 3cxpbx It says no version installed and candidate : 16.0.8.9
4. As far as I know there was no specific actions that have been taken prior to this error.
5. I have runned commands to see what 3CX services are running, they all give back a blank result/nothing.
When I run service *CXPhoneSystemMC01 start it says Failed to start 3CXPhoneSystemMC01.service: Unit 3CXPhoneSystemMC01.service not found.

I am really bewildered, I am beginning to question if the 3CX instance still exists?

If apt-cache policy reports that no version is installed then it isn't. That said, you will definitely need to re-install, in which case, I actually recommend re-installing the OS as well, especially since you're not 100% this was deployed using the 3CX ISO.

My recommendation is to install directly to the latest 3CX version which is v18 and runs on Debian 10.

If you wish to re-install v16 you can download both ISO files from the "Customer/Partner Portal >> Downloads" section.

Before proceeding, you might want to check the default backup location for any 3CX backup files and pull them off the server: /var/lib/3cxpbx/Instance1/Data/Backups

You can use a v16.0.8.9 backup file to restore your configuration on both a v16 Installation and v18 Installation. Just make sure that you use the backup file during the installation process.
