Hello all
I dont find seems error in this topic & need advice
Brief description of the problem. coolwsd service won’t start because it can’t create listening on port 9980
short supplement:
IPv6 turned ON & OFF - problem is still here.
runned in LXD container on Ubuntu 24.04
ssl.enable false
ssl.termination true
net.proto IPv4
net.listen 127.0.0.1
Hii @Vlad welcome to collabora online forum
Can you please check if the port is already in use ?
sudo lsof -i :9980
If a process is listed, terminate it
No services running on port 9980.
As u can see on early attached screenshot, only apache on 80(http) and sysresolver on 53(DNS) still working.
@Vlad can yyou recheck your network configuration settings ?
On systems where localhost resolves to IPv6 [::1] address first, when net.proto is all and net.listen is loopback, coolwsd unexpectedly listens on [::1] only.
You need to change net.proto to IPv4, if you want to use 127.0.0.1.
https://sdk.collaboraonline.com/docs/installation/Configuration.html?highlight=ipv4#network-settings
coolconfig set ssl.enable false
coolconfig set ssl.termination true
coolconfig set net.proto IPv4
coolconfig set net.listen 127.0.0.1
im turned UP IPv6 in sysctl & coolwsd.xml - problem is not resolved
Maybe LXD has some resource issue here. I see the file descriptor error in screenshot. Can you check if it’s a LXD container issue and not COOLWsd problem…
If coolwsd is running inside an LXD container:
- File Descriptor Limit: Ensure the container has sufficient file descriptors:
ulimit -n 65535
AppArmor Profiles: Check if AppArmor is blocking the process:
sudo aa-status
- If coolwsd appears under profiles in enforce mode, you may need to adjust or disable the profile.
