After upgrading flashphoner can't get it to work

[Dani]

I've used the automatic update for WebCallServer -
try to start with systemctl start get me these errors:

● webcallserver.service - Flashphoner WebCallServer
Loaded: loaded (/etc/systemd/system/webcallserver.service; enabled; vendor preset: disabled)

May 27 00:01:08 systemd[1]: webcallserver.service failed.

starting manually starts the server - but looks like it is ignoring configuration as I see no one listen on 443 and our app can't connect to the server.


After changing sudo settings - I get another error:

Good day.
Please provide SSH access to the server using this form.

Hi Max, I've reverted the server back to the old image, as the system should be kept running. I can try redoing it next week at the same time - if this is working time on your side, as I have a short window when I can keep the system "down" for debugging this.

 

[Max]

You can deploy a staging server from the image you tried to upgrade, and reproduce the issue on it. We need a permanent 24/7 access to check the server.
You can also provide an additional data: collect a report from the old image as described here and send using this form. We'll try to reproduce update issue in our test environment in this case.

 

[Dani]

I've posted the ssh details and private key. the problem occurred on the cloned server

 

[Max]

We checked your server. The logs show that it cannot bind port 443:

To fix this, please do the following:
1. Stop WCS

systemctl stop webcallserver

2. Open the file /usr/local/FlashphonerWebCallServer/bin/setenv.sh in your favourite editor

nano /usr/local/FlashphonerWebCallServer/bin/setenv.sh

3. Change

WCS_NON_ROOT=true

to

WCS_NON_ROOT=false

Save changes and close the file
4. Start WCS

systemctl stop webcallserver

Then, server should work. We've successfully tested publishing and playback on your server

 

[Dani]

is this change related to the update? it worked before this upgrade. thank you for the analysis

 

[Max]

is this change related to the update?

Yes. In latest builds, WCS main process is started from flashphoner user by default. In this case, a privileged ports (443 for example) may not be used, so it's necessary to launch the main process from root. The setting recommended above does it.

Server does work (production) but I have a strange issue:
after running systemctl start webcallserver - this is what I get as systemctl status webcallserver:


root@cyber-net bin]# systemctl status webcallserver

The server is running though.
So I'm not sure why I get active (exited) instead of active (running)

I see the same in the dev server I've created for you - should you want to inspect this yourself.

That's because systemctl can't find the pid file to monitor. This is not the error, but if you prefer to fix this, do the following:
1. Open the file /etc/systemd/system/webcallserver.service

sudo nano /etc/systemd/system/webcallserver.service

2. Change the parameter

PIDFile=/usr/local/FlashphonerWebCallServer/bin/FlashphonerMainWebCallServer.pid

to

PIDFile=/var/run/FlashphonerMainWebCallServer.pid

then save and close the file
3. Reload service units

sudo systemctl daemon-reload

4. Restart WCS service

sudo systemctl restart webcallserver

Works perfect ! Thanks.
